Salaries, wages and benefits increased $318 million, or 8.7%, in the second quarter of 2024 from the second quarter of 2023 primarily driven by higher wage rates and costs for benefit-related items associated with the ratification of a new collective bargaining agreement with our mainline pilots in August 2023. Regional expenses increased $115 million, or 10.0%, in the second quarter of 2024 from the second quarter of 2023 primarily due to an increase in regional flight operations at our wholly-owned regional carriers. An increase in the volume of engine overhauls also contributed to higher costs for maintenance, materials and repairs. Maintenance, materials and repairs increased $142 million, or 17.6%, in the second quarter of 2024 from the second quarter of 2023 primarily due to increased costs for engine overhauls, component part repairs and airframe heavy checks driven by higher volume and flight hours. Other rent and landing fees increased $72 million, or 9.5%, in the second quarter of 2024 from the second quarter of 2023 primarily driven by rate increases at certain airports and incremental engine leases. Aircraft rent decreased $30 million, or 8.6%, in the second quarter of 2024 from the second quarter of 2023 primarily due to decreased rental payments associated with aircraft operating lease extensions. Selling expenses decreased $33 million, or 6.8%, in the second quarter of 2024 from the second quarter of 2023 primarily due to a decrease in commissions expense, offset in part by higher credit card fees driven by the overall increase in passenger revenues. Other operating expenses increased $145 million, or 9.7%, in the second quarter of 2024 from the second quarter of 2023 primarily driven by the increase in flight operations, including increased costs for onboard food and catering, crew travel, ground handling and airport lounge operations, as well as certain general and administrative expenses.

Income Taxes American is a member of AAG's consolidated federal and certain state income tax returns. In 2023, American recorded an income tax provision of $394 million with an effective rate of approximately 25%, which was substantially non-cash. Substantially all of American's income before income taxes is attributable to the United States. At December 31, 2023, American had approximately $13.7 billion of gross federal NOLs and $3.6 billion of other carryforwards available to reduce future federal taxable income, of which $3.8 billion will expire beginning in 2033 if unused and $13.5 billion can be carried forward indefinitely. American also had approximately $5.3 billion of NOL carryforwards to reduce future state taxable income at December 31, 2023, which will expire in taxable years 2023 through 2043 if unused.

Total available liquidity$10,440 $11,998 $10,427 $11,985 In the ordinary course of our business, we or our affiliates may, at any time and from time to time, seek to prepay, retire or repurchase our outstanding debt through cash purchases and/or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Such repurchases, prepayments, retirements or exchanges, if any, will be conducted on such terms and at such prices as we may determine, and will depend on prevailing market conditions, our liquidity requirements, legal and contractual restrictions and other factors. The amounts involved may be material. For further information regarding our debt repurchases for the year ended December 31, 2023, see Note 4 to AAG's Consolidated Financial Statements in Part II, Item 8A and Note 3 to American's Consolidated Financial Statements in Part II, Item 8B.

Off-Balance Sheet Arrangements An off-balance sheet arrangement is any transaction, agreement or other contractual arrangement involving an unconsolidated entity under which a company has (1) made guarantees, (2) a retained or a contingent interest in transferred assets, (3) an obligation under derivative instruments classified as equity or (4) any obligation arising out of a material variable interest in an unconsolidated entity that provides financing, liquidity, market risk or credit risk support to us, or that engages in leasing, hedging or research and development arrangements with us. We have no off-balance sheet arrangements of the types described in the first three categories above that we believe may have a material current or future effect on financial condition, liquidity or results of operations. 72

(b)For variable-rate debt, future interest obligations are estimated using the current forward rates at June 30, 2024. 54 (c)Includes $7.1 billion of future principal payments and $895 million of future interest payments as of June 30, 2024, related to EETCs associated with mortgage financings of certain aircraft and spare engines. (d)See "Aircraft and Engine Purchase Commitments" above for additional information about the firm commitment aircraft delivery schedule, in particular the footnote to the table thereunder as to potential changes to such delivery schedule. Due to uncertainty surrounding the timing of delivery of certain aircraft, the amounts in the table represent our most current estimate based on contractual delivery schedules adjusted for updates and revisions to such schedules communicated to management by the applicable equipment manufacturer. However, the actual delivery schedule may differ, potentially materially, based on various potential factors including production delays by the manufacturer and regulatory concerns. Additionally, the amounts in the table exclude three and two Boeing 787 Family aircraft scheduled to be delivered in 2024 and 2025, respectively, in each case for which we have obtained committed lease financing. This financing is reflected in the operating lease commitments line above. (e)Represents minimum payments under capacity purchase agreements with third-party regional carriers. These commitments are estimates of costs based on assumed minimum levels of flying under the capacity purchase agreements and American's actual payments could differ materially. Rental payments under operating leases for certain aircraft flown under these capacity purchase agreements are reflected in the operating lease commitments line above. (f)Represents minimum pension contributions based on actuarially determined estimates as of December 31, 2023 and is based on estimated payments through 2033. During the first six months of 2024, we made required contributions of $281 million to our defined benefit pension plans. (g)Includes purchase commitments for aircraft fuel, flight equipment maintenance and information technology support and excludes obligations under certain fuel offtake agreements or other agreements for which the timing of the related expenditure is uncertain, or which are subject to material contingencies, such as the construction of a production facility.

Capital Raising Activity and Other Possible Actions In light of our significant financial commitments related to, among other things, the servicing and amortization of existing debt and equipment leasing arrangements and new flight equipment, we and our subsidiaries will regularly consider, and enter into negotiations related to, capital raising and liability management activity, which may include the entry into leasing transactions and future issuances of, and transactions designed to manage the timing and amount of, secured or unsecured debt obligations or additional equity or equity-linked securities in public or private offerings or otherwise. The cash available from operations (if any) and these sources, however, may not be sufficient to cover our cash obligations because economic factors may reduce the amount of cash generated by operations or increase costs. For instance, an economic downturn or general global instability caused by military actions, terrorism, disease outbreaks (such as the COVID-19 pandemic), natural disasters or other causes could reduce the demand for air travel, which would reduce the amount of cash generated by operations. See Part II, Item 1A. Risk Factors - "Downturns in economic conditions could adversely affect our business" for additional discussion. An increase in costs, either due to an increase in borrowing costs caused by a reduction in credit ratings or a general increase in interest rates, or due to an increase in the cost of fuel, maintenance, aircraft, aircraft engines or parts, could decrease the amount of cash available to cover cash contractual obligations. Moreover, certain of our financing arrangements contain significant minimum cash balance or similar liquidity requirements. As a result, we cannot use all of our available cash to fund operations, capital expenditures and cash obligations without violating these requirements. In the past, we have from time to time refinanced, redeemed or repurchased our debt and taken other steps to reduce or otherwise manage the aggregate amount and cost of our debt, lease and other obligations or otherwise improve our balance sheet. Going forward, depending on market conditions, our cash position and other considerations, we may continue to take such actions, and the amounts involved may be material.

(f)Total revenue per available seat mile (TRASM) - Total revenues divided by ASMs. (g)Total operating cost per available seat mile (CASM) - Total operating expenses divided by ASMs. (h)Includes aircraft owned and leased by American as well as aircraft operated by third-party regional carriers under capacity purchase agreements. Excluded from the aircraft count above are 65 regional aircraft in temporary storage as of June 30, 2024 as follows: 55 Embraer 145, eight Bombardier CRJ 700 and two Embraer 170. 41

Liquidity At June 30, 2024, AAG had $11.7 billion in total available liquidity and $875 million in restricted cash and short-term investments. Additional detail regarding our available liquidity is provided in the table below (in millions):

Certain Covenants Our debt agreements contain customary terms and conditions as well as various affirmative, negative and financial covenants that, among other things, may restrict the ability of us and our subsidiaries to incur additional indebtedness, pay dividends or repurchase stock. Our debt agreements also contain customary change of control provisions, which may require us to repay or redeem such indebtedness upon certain events constituting a change of control under the relevant agreement, in certain cases at a premium. Additionally, certain of our debt financing agreements (including our secured notes, term loans, revolving credit facilities and spare engine enhanced equipment trust certificates (EETCs)) contain loan to value (LTV) or collateral coverage ratio covenants and certain agreements require us to appraise the related collateral annually or semiannually. Pursuant to such agreements, if the applicable LTV or collateral coverage ratio exceeds or falls below a specified threshold, as the case may be, we will be required, as applicable, to pledge additional qualifying collateral (which in some cases may include cash or investment securities), withhold additional cash in certain accounts, or pay down such financing, in whole or in part, or the interest rate for the relevant financing will be increased. Additionally, a significant portion of our debt financing agreements contain covenants requiring us to maintain an aggregate of at least $2.0 billion of unrestricted cash and cash equivalents and amounts available to be drawn under revolving credit facilities, and our 5.50% senior secured notes due 2026, 5.75% senior secured notes due 2029 and AAdvantage Term Loan Facility (collectively, the AAdvantage Financing) contain a peak debt service coverage ratio, pursuant to which failure to comply with a certain threshold may result in early repayment, in whole or in part, of the AAdvantage Financing. As of the most recent applicable measurement dates, we were in compliance with each of the foregoing covenants. 51

Fuel Aircraft fuel expense was $3.1 billion in the second quarter of 2024, which was $338 million, or 12.4%, higher as compared to the second quarter of 2023. This was primarily due to an 8.8% increase in gallons of fuel consumed due to increased capacity and a 3.3% increase in the average price per gallon of aircraft fuel including related taxes to $2.70 in the second quarter of 2024 from $2.62 in the second quarter of 2023. As of June 30, 2024, we did not have any fuel hedging contracts outstanding to hedge our fuel consumption. Our current policy is not to enter into transactions to hedge our fuel consumption, although we review this policy from time to time based on market conditions and other factors. As such, and assuming we do not enter into any future transactions to hedge our fuel consumption, we will continue to be fully exposed to fluctuations in fuel prices.

Contractual Obligations The following table provides details of our estimated material cash requirements from contractual obligations as of June 30, 2024 (in millions). The table does not include commitments that are contingent on events or other factors that are uncertain or unknown at this time and is subject to other conventions as set forth in the applicable accompanying footnotes.

The commercial relationships that we have with other companies, including any related equity investments, may not produce the returns or results we expect. An important part of our strategy to expand our network has been to initiate or expand our commercial relationships with other airlines, such as by entering into global alliance, joint business and codeshare relationships, and, in certain instances, including China Southern Airlines Company Limited, GOL Linhas Aéreas Inteligentes S.A. (GOL) and JetSMART Holdings Limited, by making an equity investment in another airline in connection with initiating or expanding such a commercial relationship. We may explore additional investments in, and joint ventures and strategic alliances with, other carriers as part of our global business strategy. We face competition in forming and maintaining these commercial relationships since there are a limited number of potential arrangements and other airlines are looking to enter into similar relationships, and our inability to form or maintain these relationships, or inability to form as many of these relationships as our competitors, may have an adverse effect on our business. Any such existing or future investment could involve significant challenges and risks, including that we may not realize a satisfactory return on our investment, if any, or that they may not generate the expected revenue synergies, and they may distract management focus from our operations or other strategic options. We may also be subject to consequences from any illegal conduct of joint business partners as well as to any political or regulatory change that negatively impacts or prohibits our arrangements with any such business partners. In addition, volatility in demand for air travel, such as occurred during the COVID-19 pandemic, could materially disrupt our partners' abilities to provide air service, the timely execution of our strategic operating plans, including the finalization, approval and implementation of new strategic relationships or the maintenance or expansion of existing relationships. If any carriers with which we partner or in which we hold an equity stake were to cease trading or be declared insolvent, we could lose the value of any such investment or experience significant operational disruption, which is a risk that we are subject to with respect to our investment in and commercial arrangements with GOL in light of its commencement in January 2024 of bankruptcy proceedings in the U.S. Federal Bankruptcy Court for the Southern District of New York. These events could have a material adverse effect on our business, results of operations and financial condition. We may also from time to time pursue commercial relationships with companies outside the airline industry, which relationships may include equity investments or other financial commitments. Any such relationship or related investment could involve unique risks, particularly where these relationships involve new industry participants, emerging technologies or industries with which we are unfamiliar. Our business is very dependent on the price and availability of aircraft fuel. Continued periods of high volatility in fuel costs, increased fuel prices or significant disruptions in the supply of aircraft fuel could have a significant negative impact on consumer demand, our operating results and liquidity. Our operating results are materially impacted by changes in the availability, price volatility and cost of aircraft fuel, which represents one of the largest single cost items in our business and thus is a significant factor in the price of airline tickets. Market prices for aircraft fuel have fluctuated substantially over the past several years and prices continue to be highly volatile, with market spot prices ranging from a low of approximately $1.32 per gallon to a high of approximately $4.40 per gallon during the period from January 1, 2021 to June 30, 2024. Aircraft fuel prices reflect not only the price of underlying crude oil, but also the price charged to refine crude oil into aircraft fuel (often referred to as the "crack spread"), transportation costs, handling costs and taxes, and increases in any of these underlying components would increase the price we ultimately pay for aircraft fuel. Because of the amount of fuel needed to operate our business, even a relatively small increase or decrease in the price of fuel can have a material effect on our operating results and liquidity. Due to the competitive nature of the airline industry and unpredictability of the market for air travel, we can offer no assurance that we may be able to increase our fares, impose fuel surcharges or otherwise increase revenues or decrease other operating costs sufficiently to offset fuel price increases. Similarly, we cannot predict actions that may be taken by our competitors in response to changes in fuel prices. We cannot predict the future availability, price volatility or cost of aircraft fuel. Natural disasters (including hurricanes or similar events in the U.S. Southeast and on the Gulf Coast where a significant portion of domestic refining capacity is located), political disruptions or armed conflicts involving oil-producing countries or impacting global trade routes, changes in production levels of individual nations or associations of oil-producing states, economic sanctions imposed against oil-producing countries or specific industry participants, changes in fuel-related governmental policy, the strength of the U.S. dollar against foreign currencies, changes in the cost to transport or store petroleum products and any related staffing or transportation equipment shortages, changes in access to petroleum product pipelines and terminals, speculation in the energy futures markets, changes in aircraft fuel production capacity, environmental concerns and other unpredictable 69

events, may result in fuel supply shortages, variations in the applicable crack spread, distribution challenges, additional fuel price volatility and cost increases in the future. Any of these factors or events could cause a disruption in or increased demands on oil production, refinery operations, pipeline capacity or terminal access and possibly result in significant increases in the price of aircraft fuel and diminished availability of aircraft fuel supply. Our aviation fuel purchase contracts generally do not provide meaningful price protection against increases in fuel costs. Our current policy is not to enter into transactions to hedge our fuel consumption, although we review this policy from time to time based on market conditions and other factors. Accordingly, as of June 30, 2024, we did not have any fuel hedging contracts outstanding to hedge our fuel consumption. As such, and assuming we do not enter into any future transactions to hedge our fuel consumption, we will continue to be fully exposed to fluctuations in fuel prices. See also the discussion in Part I, Item 3. Quantitative and Qualitative Disclosures About Market Risk - "Aircraft Fuel." In addition, as part of our emissions reduction targets, we and other airlines have committed to increasing the use of SAF in our fleet. Currently, industrial production of SAF is small in scale and inadequate to meet growing industry demand, and while additional production capacity is expected to become operational in the coming years, we anticipate that competition for SAF among industry participants will remain intense. As a result, SAF may be significantly more costly than conventional jet fuel. To secure future SAF supply, we have entered into multiple agreements for the purchase of future SAF production, and we continue to engage with producers regarding potential future SAF purchases, which may include investments and other commitments to support these producers. Certain existing or potential future agreements pertain to SAF production from facilities that are planned but not yet financed, and which may utilize technology that has not been proven at commercial scale. There is no assurance that these facilities will be built or that they will meet contracted production timelines and volumes. In the event that the SAF is not delivered on schedule or in sufficient volumes, there can be no assurance that we will be able to source a supply of SAF sufficient to meet our stated goals, or that we will be able to do so on favorable economic terms. Our business is subject to extensive government regulation, which may result in increases in our costs, disruptions to our operations, limits on our operating flexibility, reductions in the demand for air travel, and competitive disadvantages. Airlines are subject to extensive domestic and international regulatory requirements. In the last several years, Congress and state and local governments have passed laws and regulatory initiatives, and the DOT, the FAA, the TSA and several of their respective international counterparts have issued regulations and a number of other directives that affect the airline industry. These requirements impose substantial costs on us and restrict the ways we may conduct our business. For example, the FAA from time to time issues directives and other regulations relating to the maintenance and operation of aircraft that require significant expenditures or operational restrictions. These requirements can be issued with little or no notice, or can otherwise impact our ability to efficiently or fully utilize our aircraft, and in some instances have resulted in the temporary and prolonged grounding of aircraft or engine types altogether including, for example, the March 2019 grounding of all Boeing 737 MAX Family aircraft, which was not lifted in the United States until November 2020, the January 2024 grounding of 737-9 MAX aircraft (a model that we do not operate), and the significant limitations imposed on the use of Pratt & Whitney GTF aircraft engines on certain Airbus aircraft (an engine that we do not use in our fleet), or otherwise caused substantial disruption and resulted in material costs to us and lost revenues. The recent telecom industry roll-out of 5G technology, and concerns regarding its possible interference with aircraft navigation systems, also resulted in regulatory uncertainty and the potential for operational impacts, including possible suspension of service to certain airports or the operation of certain aircraft, though the issue has since been resolved. See "We rely heavily on technology and automated systems to operate our business, and any failure of these technologies or systems could harm our business, results of operations and financial condition." The FAA also exercises comprehensive regulatory authority over nearly all technical aspects of our operations. Our failure to comply with such requirements has in the past and may in the future result in fines and other enforcement actions by the FAA or other regulators. In the future, any new regulatory requirements, particularly requirements that limit our ability to operate or price our products, could have a material adverse effect on us and the industry. In May 2024, Congress passed a five-year funding authorization for the FAA (FAA Authorization Renewal). Among other things, the FAA Authorization Renewal increased the authorized funding level for the FAA and required the hiring of additional air traffic controllers, an effort to address staffing and resource shortages and improve the operation of the ATC system in the U.S. The FAA Authorization Renewal also codified several consumer protection rulemakings related to refunds, vouchers and family seating that could be challenging to implement and have negative financial impacts. Any new or enhanced requirements resulting from the FAA Authorization Renewal, including any new fees, costs we may be 70

On May 1, 2021 the EU and United Kingdom entered into a new trade and cooperation agreement (the EU-UK Trade and Cooperation Agreement) to govern certain aspects of their relationship following Brexit. We face risks associated with Brexit, notably given the extent of our passenger and cargo traffic and that of our joint business partners that flows through LHR in the United Kingdom. The EU-UK Trade and Cooperation Agreement includes provisions in relation to commercial air service that we expect to be sufficient to sustain our current services under the transatlantic joint business. However, the scope of traffic rights under the EU-UK Trade and Cooperation Agreement is less extensive than before Brexit and therefore the full impact of the EU-UK Trade and Cooperation Agreement is uncertain. For example, on December 4, 2023, the United Kingdom government launched a consultation on the reform of the rules applicable to airport slots in the United Kingdom. At this stage, the impact of this consultation and any consequent changes to the United Kingdom slot rules on our operations or those of our joint business partners at LHR is uncertain, but could be material. As a result, the continuation of our current services, and those of our partners could be disrupted. This could materially adversely affect our business, results of operations and financial condition. More generally, changes in U.S. or foreign government aviation policies could result in the alteration or termination of such agreements, diminish the value of route authorities, slots or other assets located abroad, or otherwise adversely affect our international operations. We operate a global business with international operations that are subject to economic and political instability and have been, and in the future may continue to be, adversely affected by numerous events, circumstances or government actions beyond our control. We operate a global business with significant operations outside of the U.S. Our current international activities and prospects have been, and in the future could be, adversely affected by government policies, reversals or delays in the opening of foreign markets, increased competition in international markets, the performance of our alliance, joint business and codeshare partners in a given market, exchange controls or other restrictions on repatriation of funds, currency and political risks (including changes in exchange rates and currency devaluations), environmental regulation, increases in taxes and fees and changes in international governmental regulation of our operations, including the inability to obtain or retain needed route authorities and/or slots, and new or evolved policies related to consumer protections. In particular, the COVID-19 pandemic severely impacted the demand for international travel for a prolonged period, and resulted in the imposition of significant governmental restrictions on commercial air service to or from certain regions. We responded by temporarily suspending a significant portion of our long-haul international flights and delaying the introduction of certain new long-haul international routes. While many countries have largely eliminated their pandemic restrictions, we can provide no assurance as to when demand for international travel will return to pre-COVID-19 pandemic levels in certain markets, if at all, or whether certain international destinations we previously served will be economical in the future. We are subject to varying registration requirements and ongoing reporting obligations in the countries where we operate. Our permission to continue doing business in these countries may depend on our ability to timely fulfil or remedy any noncompliance with these and other governmental requirements. We may also be subject to the risk that relevant government agencies will be delayed in granting or renewing required approvals, including as a result of shutdowns (such as occurred in certain jurisdictions during the COVID-19 pandemic), cybersecurity incidents or other events. Any lapse, revocation, suspension or delay in approval of our authority to do business in a given jurisdiction may prevent us from serving certain destinations and could adversely impact our business, financial condition and results of operations. More generally, our industry may be affected by any deterioration in global trade relations, including shifts in the trade policies of individual nations. For example, much of the demand for international air travel is the result of business travel in support of global trade. Should protectionist governmental policies, such as increased tariff or other trade barriers, travel limitations and other regulatory actions, have the effect of reducing global commercial activity, the result could be a material decrease in the demand for international air travel. Additionally, certain of the products and services that we purchase, including certain of our aircraft and related parts, are sourced from suppliers located outside the U.S., and the imposition of new tariffs, or any increase in existing tariffs, by the U.S. government in respect of the importation of such products could materially increase the amounts we pay for them. We face risks associated with Brexit, notably given the extent of our passenger and cargo traffic and that of our joint business partners that flows through LHR in the United Kingdom. The EU-UK Trade and Cooperation Agreement includes provisions in relation to commercial air service that we expect to be sufficient to sustain our current services under the transatlantic joint business. However, the scope of traffic rights under the EU-UK Trade and Cooperation Agreement is less extensive than before Brexit and therefore the full impact of the EU-UK Trade and Cooperation Agreement is uncertain. As a result, the continuation of our current services, and those of our partners could be disrupted. Moreover, 36

We are subject to risks associated with climate change, including increased regulation of our GHG emissions, changing consumer preferences and the potential for increased impacts of severe weather events on our operations and infrastructure. Efforts to combat climate change have increased the focus by regulators worldwide on the need to reduce GHG emissions, including those from the airline industry. Concerns over GHG emissions are likely to result in continued attempts to adopt requirements or change business environments related to aviation that, if successful, may result in increased costs to the airline industry and us. In addition, several countries and U.S. states have adopted or are considering adopting programs, including potentially new taxes, to regulate GHG emissions. In addition, certain airports have proposed, and could in the future adopt, GHG emission or climate-related goals or measures that could impact our operations or require us to make changes or investments in our infrastructure. In particular, ICAO has adopted rules, including those pertaining to CORSIA, which will require us to mitigate the growth of GHG emissions associated with a significant majority of our international flights. At this time, the costs of complying with our future obligations under CORSIA are uncertain, primarily due to significant uncertainty with respect to the future growth of covered GHG emissions, the supply and price of eligible carbon credits and the future development of the market for eligible renewable fuels. Due to the competitive nature of the airline industry and unpredictability of the market for air travel, we can offer no assurance that we may be able to increase our fares, impose surcharges or otherwise increase revenues or decrease other operating costs sufficiently to offset the costs of meeting our obligations under CORSIA. Due to the uncertainty surrounding the applicability of CORSIA to our operations in the long-term, along with the recent implementation of and potential for other new regulatory initiatives to reduce airline GHG emissions, we and other airlines are increasingly subject to an unpredictable and inconsistent array of national or regional emissions restrictions, creating a patchwork of complex regulatory requirements that could lead to increased expenses related to the emissions of our flights. For more information on these regulatory developments, see "Aircraft Emissions and Climate Change Requirements" under Part I, Item 1. Business - "Domestic and Global Regulatory Landscape - Environmental Matters." In addition, as part of our emissions reduction targets, we and other airlines have committed to increasing the use of SAF in our fleet. Currently, industrial production of SAF is small in scale and inadequate to meet growing industry demand, and while additional production capacity is expected to become operational in the coming years, we anticipate that competition for SAF among industry participants will remain intense. As a result, SAF may be significantly more costly than conventional jet fuel. To secure future SAF supply, we have entered into multiple agreements for the purchase of future SAF production, and we continue to engage with producers regarding potential future SAF purchases, which may include investments and other commitments to support these producers. Certain existing or potential future agreements pertain to SAF production from facilities that are planned but not yet financed, and which may utilize technology that has not been proven at commercial scale. There is no assurance that these facilities will be built or that they will meet contracted production timelines and volumes. In the event that the SAF is not delivered on schedule or in sufficient volumes, there can be no assurance that we will be able to source a supply of SAF sufficient to meet our stated goals, or that we will be able to do so on favorable economic terms. Additionally, growing recognition among consumers of the dangers of climate change may mean some customers choose to fly less frequently or fly on an airline they perceive as operating in a manner that is more sustainable to the climate. Business customers may choose to use alternatives to travel, such as virtual meetings and workspaces. Greater development of high-speed rail in markets now served by short-haul flights could provide passengers with lower-carbon alternatives to flying with us. Customers may also elect to travel on flights that produce comparatively fewer GHG emissions, particularly after commencement of the EU environmental labelling scheme for flights in 2025. Our collateral to secure loans, in the form of aircraft, spare parts and airport slots, could lose value as customer demand shifts and economies move to low-carbon alternatives, which may increase our financing cost. We have published a number of sustainability-related targets and goals, including with respect to reducing our GHG emissions. These goals are often long-term in nature, and in many cases rely on assumptions about the future availability and efficacy of technologies that do not yet exist or are not yet commercially viable. Our ability to meet our publicly stated targets is dependent on a number of factors outside our control, including the ability of third parties, such as engine and airframe manufacturers, SAF producers and other industry participants, to timely develop and commercialize these technological solutions. Additionally, we face risks associated with allegations or similar claims that our public statements concerning our sustainability efforts and achievements are exaggerated or unsubstantiated, sometimes referred to as "greenwashing," and could be subject to litigation or regulatory enforcement actions challenging the basis for such statements which could be costly and disruptive, whether or not meritorious. 38

•super-majority voting requirements to modify or amend specified provisions of our Certificate of Incorporation. 48 These provisions are not intended to prevent a takeover, but are intended to protect and maximize the value of the interests of our stockholders. While these provisions have the effect of encouraging persons seeking to acquire control of our company to negotiate with our Board of Directors, they could enable our Board of Directors to prevent a transaction that some, or a majority, of our stockholders might believe to be in their best interest and, in that case, may prevent or discourage attempts to remove and replace incumbent directors. In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law, which prohibits business combinations with interested stockholders. Interested stockholders do not include stockholders whose acquisition of our securities is approved by the Board of Directors prior to the investment under Section 203. The issuance or sale of shares of our common stock, rights to acquire shares of our common stock, or warrants issued to the U.S. Department of Treasury under the CARES Act, the PSP Extension Law, the ARP, PSP1, PSP2 and PSP3, could depress the trading price of our common stock and the Convertible Notes. We may conduct future offerings of material amounts of our common stock, preferred stock or other securities that are convertible into or exercisable for our common stock to finance our operations, to fund acquisitions, or for any other purposes at any time and from time to time (including as compensation to the U.S. Government for the proceeds received pursuant to the payroll support program established under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) (PSP1), the payroll support program established under the Subtitle A of Title IV of Division N of the Consolidated Appropriations Act, 2021 (PSP Extension Law) (PSP2) and the payroll support program established under the American Rescue Plan Act of 2021 (ARP) (PSP3)). If these additional shares or securities are issued or sold, or if it is perceived that they will be sold, into the public market or otherwise, the trading price of our common stock and the 6.50% convertible senior notes due 2025 (the Convertible Notes) could decline substantially. If we issue additional shares of our common stock or rights to acquire shares of our common stock, if any of our existing stockholders sells a substantial amount of our common stock, or if the market perceives that such issuances or sales may occur, then the trading price of our common stock and the Convertible Notes could decline substantially.

We may be a party to litigation in the normal course of business or otherwise, which could affect our financial position and liquidity. From time to time, we are a party to or otherwise involved in legal proceedings, claims and government inspections or investigations and other legal matters, both inside and outside the United States, arising in the ordinary course of our business or otherwise. We are currently involved in various legal proceedings and claims that have not yet been fully resolved, and additional claims may arise in the future. Legal proceedings can be complex and take many months, or even years, to reach resolution, with the final outcome depending on a number of variables, some of which are not within our control. Litigation is subject to significant uncertainty and may be expensive, time-consuming, and disruptive to our operations. Although we will vigorously defend ourselves in such legal proceedings, their ultimate resolution and potential financial and other impacts on us are uncertain. For these and other reasons, we may choose to settle legal proceedings and claims, regardless of their actual merit. If a legal proceeding is resolved against us, it could result in significant compensatory damages, and in certain circumstances punitive or trebled damages, disgorgement of revenue or profits, remedial corporate measures or injunctive relief imposed on us. If our existing insurance does not cover the amount or types of damages awarded, or if other resolution or actions taken as a result of the legal proceeding were to restrain our ability to operate or market our services, our consolidated financial position, results of operations or cash flows could be materially adversely affected. In addition, legal proceedings, and any adverse resolution thereof, can result in adverse publicity and damage to our reputation, which could adversely impact our business. Additional information regarding certain legal matters in which we are involved can be found in Note 12 to each of AAG's and American's Condensed Consolidated Financial Statements in Part I, Item 1A and Part I, Item 1B, respectively.

New U.S. tax legislation may adversely affect our financial condition, results of operations and cash flows. We are subject to taxation at the federal, state and local levels in the United States. The U.S. government may enact significant changes to the taxation of business entities. For example, on August 16, 2022, the Inflation Reduction Act was signed into law, introducing, among other changes, a corporate minimum tax on certain corporations and an excise tax on certain stock repurchases by certain corporations. With numerous provisions of the Tax Cuts and Jobs Act set to expire in 2025, we expect that consideration of legislation related to tax laws is likely in coming quarters, but the likelihood of any proposed changes to the tax law being enacted or implemented is unclear, and we are currently unable to predict whether such changes will occur. If changes to tax laws are implemented, we are currently unable to predict the ultimate impact on our business and therefore there can be no assurance our business will not be adversely affected. We have a significant amount of goodwill, which is assessed for impairment at least annually. In addition, we may never realize the full value of our intangible assets or long-lived assets, causing us to record material impairment charges. Goodwill and indefinite-lived intangible assets are not amortized, but are assessed for impairment at least annually, or more frequently if conditions indicate that an impairment may have occurred. In accordance with applicable accounting standards, we first assess qualitative factors to determine whether it is necessary to perform a quantitative impairment test. In addition, we are required to assess certain of our other long-lived assets for impairment if conditions indicate that an impairment may have occurred. Future impairment of goodwill, intangible assets or other long-lived assets could be recorded in results of operations as a result of changes in assumptions, estimates, or circumstances, some of which are beyond our control. There can be no assurance that a material impairment charge of goodwill or tangible or intangible assets will be avoided. The value of our aircraft could be impacted in future periods by changes in supply and demand for these aircraft. Such changes in supply and demand for certain aircraft types could result from grounding of aircraft by us or other airlines, including as a result of significant or prolonged declines in demand for air travel and corresponding reductions to capacity. We can provide no assurance that a material impairment loss of tangible or intangible assets will not occur in a future period; we have previously incurred significant impairment charges associated with our decision to retire certain aircraft as a result of the severe decline in demand for air travel due to the COVID-19 pandemic, and the risk of future material impairments remains uncertain. Such impairment charges could have a material adverse effect on our business, results of operations and financial condition. 68

•the adoption of more restrictive locally-imposed noise restrictions; and 71 •restrictions on travel or special guidelines regarding aircraft occupancy or hygiene in response to outbreaks of illness, such as occurred during the COVID-19 pandemic, including the imposition of preflight testing regimes or vaccination confirmation requirements which have in the past and may in the future have the effect of reducing demand for air travel in the markets where such requirements are imposed. Each additional regulation or other form of regulatory oversight increases costs and adds greater complexity to airline operations and, in some cases, may reduce the demand for air travel. There can be no assurance that the increased costs or greater complexity associated with our compliance with new rules, anticipated rules or other forms of regulatory oversight will not have a material adverse effect on us. Any significant reduction in air traffic capacity at and in the airspace serving key airports in the U.S. or overseas could have a material adverse effect on our business, results of operations and financial condition. In addition, the ATC system is not successfully modernizing to meet the growing demand for U.S. air travel. Air traffic controllers rely on outdated procedures and technologies that routinely compel airlines, including ourselves, to fly inefficient routes or take significant delays on the ground. The ATC system's inability to manage existing travel demand, including due to significant staffing shortages, has led government agencies to implement short-term capacity constraints during peak travel periods or adverse weather conditions in certain markets, resulting in delays and disruptions of air traffic. The outdated technologies also cause the ATC system to be less resilient in the event of a failure, and past system disruptions have resulted in large-scale flight cancellations and delays. We experienced this challenge in January 2023 when an outage in the ATC Notice to Air Missions system led to a nationwide ground-stop for nearly two hours, resulting in significant operational disruption throughout the day. In the early 2000s, the FAA embarked on a path to modernize the national airspace system, including migration from the current radar-based ATC system to a GPS-based system. This modernization of the ATC system, generally referred to as "NextGen," has been plagued by delays and cost overruns, and it remains uncertain when the full array of benefits expected from this modernization will be available to the public and the airlines, including ourselves. Failure to update the ATC system and the substantial costs that may be imposed on airlines, including ourselves, to fund a modernized ATC system may have a material adverse effect on our business. Further, our business has been adversely impacted when government agencies have ceased to operate as expected, including due to partial shutdowns, sequestrations or similar events and the COVID-19 pandemic. These events have resulted in, among other things, reduced demand for air travel, an actual or perceived reduction in air traffic control and security screening resources and related travel delays, as well as disruption in the ability of the FAA to grant required regulatory approvals, such as those that are involved when a new aircraft is first placed into service. Our operating authority in international markets is subject to aviation agreements between the U.S. and the respective countries or governmental authorities, such as the EU, and in some cases, fares and schedules require the approval of the DOT and/or the relevant foreign governments. Moreover, alliances with international carriers may be subject to the jurisdiction and regulations of various foreign agencies. The U.S. government has negotiated "open skies" agreements with more than 130 trading partners, which agreements allow unrestricted route authority access between the U.S. and the foreign markets. While the U.S. has worked to increase the number of countries with which open skies agreements are in effect, a number of markets important to us, including China, do not have open skies agreements. For example, the open skies air services agreement between the U.S. and the EU, which took effect in March 2008, provides airlines from the U.S. and EU member states open access to each other's markets, with freedom of pricing and unlimited rights to fly from the U.S. to any airport in the EU. As a result of the agreement and a subsequent open skies agreement involving the U.S. and the United Kingdom, which was agreed in anticipation of Brexit, we face increased competition in these markets, including LHR. Bilateral and multilateral agreements among the U.S. and various foreign governments of countries we serve but which are not covered by an open skies treaty are subject to periodic renegotiation. We currently operate a number of international routes under government arrangements that limit the number of airlines permitted to operate on the route, the capacity of the airlines providing services on the route, or the number of airlines allowed access to particular airports. If an open skies policy were to be adopted for any of these markets, it could adversely impact us and could result in impairments of our related tangible and intangible assets. In addition, competition from foreign airlines, revenue-sharing joint ventures, joint business agreements, and other alliance arrangements by and among other airlines could impair the value of our business and assets on the open skies routes. On May 1, 2021 the EU and United Kingdom entered into a new trade and cooperation agreement (the EU-UK Trade and Cooperation Agreement) to govern certain aspects of their relationship following Brexit. We face risks associated with Brexit, notably given the extent of our passenger and cargo traffic and that of our joint business partners that flows 72

These and other factors contributed to a prolonged shortage of qualified, entry-level pilots, shortages of experienced pilots trained and ready for duty, principally at our regional affiliates, and increased compensation costs materially for pilots throughout the industry. While progress has been made in improving pilot staffing, we believe that this industry-wide pilot shortage will remain a problem, in particular for regional airlines in the United States, for the foreseeable future. We have recently implemented a number of recruitment initiatives intended to recruit qualified pilots to our regional airlines, including offering significant financial incentives, but we cannot guarantee that such efforts will be successful. Notwithstanding these efforts, our regional airline subsidiaries and other regional partners have recently been unable to hire adequate numbers of pilots to meet their needs, resulting in a reduction in the number of flights offered, operational disruptions, increased compensation expense and costs of operations, financial difficulties and other adverse effects. We depend on a limited number of suppliers for aircraft, aircraft engines and parts. Delays in scheduled aircraft deliveries, unexpected grounding of aircraft or aircraft engines whether by regulators or by us, or other loss of anticipated fleet capacity, and failure of new aircraft to receive regulatory approval, be produced or otherwise perform as and when expected, adversely impacts our business, results of operations and financial condition. We depend on a limited number of suppliers for aircraft, aircraft engines and many aircraft and engine parts. For example, all of our mainline aircraft were manufactured by either Airbus or Boeing and all of our regional aircraft were manufactured by either Bombardier or Embraer. Further, our supplier base continues to consolidate as evidenced by recent transactions involving Airbus and Bombardier and Mitsubishi and Bombardier, and the cessation of production of certain Bombardier regional aircraft that we and our regional partners currently operate in large numbers. Due to the limited number of suppliers, constraints on production capacity, large order books and long production lead times, manufacturers have faced and are expected to continue to face challenges in timely fulfilling our aircraft on order, and we may face competition from other carriers in securing an adequate supply of aircraft in the future. If new aircraft orders are not filled on a timely basis, we could face higher financing and operating costs than planned. The limited number of these suppliers may also result in reduced competition and potentially higher prices than if the supplier base was less concentrated. In addition, we are vulnerable to any problems associated with the performance of these suppliers' obligation to supply key aircraft, parts and engines, including design defects, mechanical problems, contractual performance by suppliers or adverse perception by the public that would result in customer avoidance of any of our aircraft. If the aircraft we receive do not meet expected performance or quality standards, including with respect to fuel efficiency, safety and reliability, we could also face higher financing and operating costs than planned and our business, results of operations and financial condition could be adversely impacted. We are also subject to the risk that action by the FAA or any other regulatory authority could result in an inability to certify or operate our aircraft, even temporarily. For instance, in March 2019, the FAA ordered the grounding of all Boeing 737 MAX Family aircraft, which remained in place for over a year and was not lifted in the United States until November 2020. An additional grounding of Boeing aircraft occurred in January 2024 involving the Boeing 737-9 MAX, a model that we do not operate. Further, significant limitations imposed on the use of Pratt & Whitney GTF aircraft engines (an engine that we do not use in our fleet) on certain Airbus aircraft have resulted in very significant numbers of the related aircraft being grounded while awaiting refurbished engines. Regulatory concerns raised by the FAA also previously forced Boeing to suspend deliveries of certain 787 aircraft, temporarily resulting in significant reductions to our planned long-haul flying. More generally, we have recently experienced delivery delays across manufacturers due to regulatory matters such as those described above, regulatory restrictions on production rate increases (such as those that the FAA has recently imposed on Boeing 737 production), supply chain limitations, development delays, and other factors, which have created significant challenges in planning our fleet, and those challenges are likely to continue. There is also the prospect that new aircraft models will continue to face certification delays further impeding the delivery of new aircraft to the airline industry and increasing competition for the production capacity that is available. 77

We are subject to many forms of environmental and noise regulation and may incur substantial costs as a result. We are subject to a number of increasingly stringent federal, state, local and foreign laws, regulations and ordinances relating to the protection of human health and the environment and noise reduction, including those relating to emissions to the air, discharges to land and surface and subsurface waters, safe drinking water, and the management of hazardous substances, oils and waste materials. This universe of substances is evolving to encompass many substances not previously regulated. Compliance with environmental laws and regulations can require significant expenditures, and violations can lead to significant fines and penalties, as well as civil liability. We are also subject to other environmental laws and regulations, including those that require us to investigate and remediate soil or groundwater to meet certain remediation standards. Under federal law, generators of waste materials, and current and former owners or operators of facilities, can be subject to liability for investigation and remediation costs at locations that have been identified as requiring response actions. Liability under these laws may be retroactive, strict, joint and several, meaning that we could be liable for the costs of cleaning up environmental contamination regardless of when it occurred, fault or the amount of waste directly attributable to us. We have liability for investigation and remediation costs at various domestic sites, although such costs currently are not expected to have a material adverse effect on our business. Governmental authorities in the U.S. and abroad are increasingly focused on potential contamination resulting from the use of certain chemicals, most notably per- and polyfluoroalkyl, substances (PFAS). Products containing PFAS have been used in manufacturing, industrial, and consumer applications over many decades, including those related to aviation. Among other things, recent changes to federal requirements for firefighting foams containing PFAS, as well as related state regulations affecting their use, will require operational and infrastructure changes. In February 2024, the EPA published, for public comment, a new rulemaking to list nine PFAS as hazardous constituents under the Resource Conservation and Recovery Act. In April 2024, the EPA published a final rule designating two PFAS substances (perfluorooctanoic acid and perfluorooctanesulfonic acid) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act. This new rule requires entities to immediately report current and past releases of such substances that meet or exceed the reportable quantity to EPA's National Response Center. These rulemakings could require additional oversight and management of PFAS-containing waste. We may incur costs in connection with current and future reporting obligations, costs related to materials management and historic usage and disposal of PFAS-containing materials, transitioning away from the usage of PFAS-containing products and firefighting systems, or remediating any environmental impacts. We have various leases and agreements with respect to real property, tanks and pipelines with airports and other operators. Under these leases and agreements, we have agreed to indemnify the lessor or operator against environmental liabilities associated with the real property or operations described under the agreement, even in certain cases where we are not the party responsible for the initial event that caused the environmental damage. We also participate in leases with other airlines in fuel consortiums and fuel committees at airports, and such indemnities are generally joint and several among the participating airlines. Governmental authorities in several U.S. and foreign cities are also considering, or have already implemented, aircraft noise reduction programs, including the imposition of nighttime curfews and limitations on daytime take offs and landings as well as setting an annual flight cap from specific cities. We have been able to accommodate local noise restrictions imposed to date, but our operations could be adversely affected if locally-imposed regulations become more restrictive or widespread. The FAA is also currently evaluating possible changes to how aircraft noise is measured, and the resulting standards that are based on them. Ultimately, these changes could have an impact on, or limit, our operations, or make it more difficult for the FAA to modernize and increase the efficiency of the airspace and airports we utilize. 76 A high level of pilot retirements, more stringent duty time regulations, increased flight hour requirements for commercial airline pilots, reductions in the number of military pilots entering the commercial workforce, increased training requirements and other factors have caused a shortage of pilots that could materially adversely affect our business. Commencing in 2013, the minimum flight hour requirement to achieve a commercial pilot's license in the United States increased from 250 to 1,500 hours, thereby significantly increasing the time and cost commitment required to become licensed to fly commercial aircraft. Additionally, the number of military pilots being trained by the U.S. armed forces and available as commercial pilots upon their retirement from military service has been decreasing. Further, in the course of the domestic airline industry rapidly restoring capacity during the recovery from the COVID-19 pandemic, the significant training requirements to return large numbers of pilots to active flying have been time consuming and disruptive.

The success of our business depends on, among other things, effectively managing the number and types of aircraft we operate. If, for any reason, we are unable to accept or secure deliveries of new aircraft on contractually scheduled delivery timelines, our business, results of operations and financial condition could be negatively impacted. Our failure to integrate newly purchased aircraft into our fleet as planned might require us to seek extensions of the terms for some leased aircraft or otherwise delay the exit of certain aircraft from our fleet, and in certain cases, may require us to undertake costly refurbishments or maintenance of such aircraft. Such unanticipated extensions or delays, which as noted above have recently been relatively commonplace among manufacturers of commercial aircraft, may require us to operate existing aircraft beyond the point at which it is economically optimal to retire them, resulting in increased maintenance costs, or reductions to our schedule, thereby reducing revenues. Repeated or prolonged delays in the production, delivery or induction of our new aircraft could also require us to scale back our growth plans, reduce frequencies or forgo service entirely to certain markets, which could adversely affect our business, financial condition and results of operations. We rely heavily on technology and automated systems to operate our business, and any failure of these technologies or systems could harm our business, results of operations and financial condition. We are highly dependent on existing and emerging technology and automated systems to operate our business. These technologies and systems include but may not be limited to our computerized airline reservation system, flight operations and crew scheduling systems, financial planning, management and accounting systems, telecommunications systems, website, maintenance systems and check-in kiosks. In order for our operations to work efficiently, our website and reservation system must be able to accommodate a high volume of traffic, maintain secure information and deliver flight information, as well as issue electronic tickets and process critical financial information in a timely manner. Substantially all of our tickets are issued to passengers as electronic tickets. We depend on our reservation system, which is hosted and maintained under a long-term contract by a third-party service provider, to be able to issue, track and accept these electronic tickets. If our technologies or automated systems are not functioning or if our third-party service providers were to fail to adequately provide technical support, system maintenance or timely software upgrades for any one of our key existing systems, we could experience service disruptions or delays, which could harm our business and result in the loss of important data, increase our expenses and decrease our revenues. Furthermore, certain critical aspects of our operation rely on legacy technological systems which may grow more difficult or expensive to support and maintain over time, and such systems may fail to perform as required or become more vulnerable to malfunction or failure over time. In the event that one or more of our primary technology or systems vendors goes into bankruptcy, ceases operations or fails to perform as promised, replacement services may not be readily available on a timely basis, at competitive rates or at all, and any transition time to a new system may be significant. Our aircraft employ a number of sophisticated radio and satellite-based navigation and safety technologies, and we are subject to risks associated with the introduction or expansion of technologies that could interfere with the safe operation of these flight systems. For example, telecommunications companies are expanding and increasing the commercial and consumer applications of 5G cellular communication networks, and regulators, manufacturers and operators have expressed concerns that certain 5G applications could interfere with certain flight systems. On December 23, 2021, the FAA issued a special airworthiness information bulletin (SAIB), in which it indicated that further testing and assessment is needed regarding the effects of 5G on certain aircraft equipped with radar altimeters, which measure the aircraft's altitude and guide pilots during landings. If it were determined that 5G signals posed an interference risk to these altimeters or other systems, the FAA indicated in its SAIB that it could restrict flight operations in areas where such interference could occur. On June 17, 2022, the FAA and the telecommunications industry reached an agreement to delay the full implementation of 5G deployment near airports until July 1, 2023. The delayed implementation allowed the aviation industry time to retrofit the radio altimeters on aircraft to prevent potential interference from 5G signals. American has completed the retrofit of its impacted mainline and regional aircraft, and we now expect operational certainty as it pertains to 5G until 2028, when the current operating agreement between the FAA, Federal Communications Commission and the telecommunications industry expires.

We rely on third-party distribution channels and must effectively manage the costs, rights and functionality of these channels. While our priority is to migrate an increasing portion of our customers to our modern, direct distribution channels in lieu of third party channels, we continue to rely on third-party distribution channels, including those provided by or through global distribution systems (GDSs) (e.g., Amadeus, Sabre and Travelport), conventional travel agents, travel management companies and online travel agents (OTAs) (e.g., Expedia, including its booking sites Orbitz and Travelocity, and Booking Holdings, including its booking sites Kayak and Priceline), to distribute a significant portion of our airline tickets, and we expect in the future to continue to rely on these channels. We are also dependent upon the ability and willingness of these distribution channels to expand their ability to distribute and collect revenues for ancillary products (e.g., fees for selective seating). These distribution channels are more expensive and at present have less functionality in respect of ancillary product offerings than those we operate ourselves, such as our website at www.aa.com. Certain of these distribution channels also effectively restrict the manner in which we distribute our products generally. To remain competitive, we will need to manage successfully our distribution costs and rights, increase our distribution flexibility, continue to migrate the distribution of tickets to our proprietary and other modern distribution channels, and improve the functionality of our distribution channels, while maintaining an industry-competitive cost structure and a high level of customer satisfaction. Further, as distribution technology changes we will need to continue to update our technology by acquiring new technology from third parties, building the functionality ourselves, or a combination, which in any event will likely entail significant technological and commercial risk and involve potentially material investments. These imperatives may affect our relationships with conventional travel agents, travel management companies, GDSs and OTAs, including if consolidation of conventional travel agents, travel management companies, GDSs or OTAs continues, or should any of these parties seek to acquire other technology providers thereby potentially limiting our technology alternatives. For example, as previously reported, during the second quarter of 2024 we concluded that certain commercial initiatives designed to, among other things, migrate customers to our modern, direct distribution channels contributed to softness in customer bookings relative to our expectations, and we reversed many of these measures late in the quarter. Any inability to manage our third-party distribution costs, rights and functionality at a competitive level or any material diminishment or disruption in the distribution of our tickets could have a material adverse effect on our business, results of operations and financial condition. If we are unable to obtain and maintain adequate facilities and infrastructure throughout our system and, at some airports, adequate slots, we may be unable to operate our existing flight schedule and to expand or change our route network in the future, which may have a material adverse impact on our operations. In order to operate our existing and proposed flight schedule and, where desirable, add service along new or existing routes, we must be able to maintain and/or obtain adequate gates, check-in counters, operations areas, operations control facilities and administrative support space. As airports around the world become more congested, it may not be possible for us to ensure that our plans for new service can be implemented in a commercially viable manner, given operating constraints at airports throughout our network, including those imposed by inadequate facilities at desirable airports. In light of constraints on existing facilities, there is presently a significant amount of capital spending underway at major airports in the United States, including large projects underway at a number of airports where we have significant operations, such as O'Hare International Airport, Dallas/Fort Worth International Airport and Los Angeles International Airport. More generally, following long periods of underinvestment, there is a trend among airports in the United States to engage in significant, expensive expansion, remodeling and infrastructure improvement projects. This spending is 81 expected to result in increased costs to airlines and the traveling public that use those facilities as the airports seek to recover their investments through increased rental, landing and other facility costs. In some circumstances, such costs could be imposed by the relevant airport authority without our approval. Accordingly, our operating costs are expected to increase significantly at many airports at which we operate, including a number of our hubs and gateways, as a result of capital spending projects currently underway and additional projects that we expect to commence over the next several years.

Risks Related to Ownership of AAG Common Stock and Convertible Notes The price of AAG common stock has been and may in the future be volatile. The market price of AAG common stock has fluctuated substantially in the past, and may fluctuate substantially in the future, due to a variety of factors, many of which are beyond our control, including: •the effects of external events, such as the COVID-19 pandemic, on our business or the U.S. and global economies; •macro-economic conditions, including the price of fuel; •changes in market values of airline companies as well as general market conditions; •our operating and financial results failing to meet the expectations of securities analysts or investors; •changes in financial estimates or recommendations by securities analysts; •changes in our level of outstanding indebtedness and other obligations; •changes in our credit ratings; •material announcements by us or our competitors; 83 •expectations regarding any future capital deployment program, including share repurchase programs and any future dividend payments that may be declared by our Board of Directors, or any subsequent determination to cease repurchasing stock or paying dividends; •new regulatory pronouncements and changes in regulatory guidelines; •general and industry-specific economic conditions; •changes in our key personnel; •inclusion of our common stock in broad market indexes favored by passive investors; •investor preferences to invest in certain sectors, including large technology companies in lieu of industrial or transportation companies; •public or private sales of a substantial number of shares of AAG common stock or issuances of AAG common stock upon the exercise or conversion of restricted stock unit awards, stock appreciation rights, or other securities that may be issued from time to time, including warrants we have issued in connection with our receipt of funds under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), Subtitle A of Title IV of Division N of the Consolidated Appropriations Act, 2021 (the PSP Extension Law) and the American Rescue Plan Act of 2021 (ARP); •increases or decreases in reported holdings by insiders or other significant stockholders;

•fluctuations in trading volume; and •technical factors in the public trading market for our stock that may produce price movements that may or may not comport with macro, industry or company-specific fundamentals, including, without limitation, the sentiment of retail investors (including as may be expressed on financial trading and other social media sites), the amount and status of short interest in our securities, access to margin debt, trading in options and other derivatives on our common stock and any related hedging and other technical trading factors. The closing price of our common stock on the Nasdaq Global Select Market varied from $10.92 to $18.80 during 2023 and $10.58 to $15.68 during 2024 year-to-date through July 19, 2024. At times, fluctuations in our stock price have been rapid, imposing risks on investors due to the possibility of significant, short-term price volatility. While we believe that in recent years this wide range of trading prices has largely reflected the changing prospects for a large airline facing the challenges imposed by the COVID-19 pandemic, we also believe, based in part on the commentary of market analysts, that the trading price of our common stock has at times been influenced by the technical trading factors discussed in the last bullet above. On some occasions, market analysts have explained fluctuations in our stock price by reference to purported "short squeeze" activity. A "short squeeze" is a technical market condition that occurs when the price of a stock increases substantially, forcing market participants who had taken a position that its price would fall (i.e., who had sold the stock "short"), to buy it, which in turn may create significant, short-term demand for the stock not for fundamental reasons, but rather due to the need for such market participants to acquire the stock in order to forestall the risk of even greater losses. A "short squeeze" condition in the market for a stock can lead to short-term conditions involving very high volatility and trading that may or may not track fundamental valuation models. If we decide to make repurchases of or pay dividends on our common stock, we cannot guarantee that we will continue to do so or that such a capital deployment program will enhance long-term stockholder value. If we determine to make any share repurchases in the future, such repurchases may be made through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades or accelerated share repurchase transactions. Our future repurchases of AAG common stock, if any, may be limited, suspended or discontinued at any time at our discretion and without prior notice. If we determine to make any dividends in the future, such dividends that may be declared and paid from time to time will be subject to market and economic conditions, applicable legal requirements and other relevant factors. The amount and timing of any future dividends, if any, may vary, and the payment of any dividend does not assure that we will pay dividends in the future. In addition, any future repurchases of AAG common stock or payment of dividends, or any determination to cease repurchasing stock or paying dividends, could affect our stock price and increase its volatility. The existence of a future 84 share repurchase program and any future dividends could cause our stock price to be higher than it would otherwise be and could potentially reduce the market liquidity for our stock. Additionally, any future repurchases of AAG common stock or payment of dividends will diminish our cash reserves, which may impact our ability to finance future growth and to pursue possible future strategic opportunities and acquisitions. Further, our repurchase of AAG common stock may fluctuate such that our cash flow may be insufficient to fully cover our share repurchases. We generally are subject to an excise tax on the fair market value of AAG common stock repurchased (less the fair market value of AAG common stock issued and subject to certain adjustments and exceptions) during any year after December 31, 2022. Although our share repurchase programs are intended to enhance long-term stockholder value, there is no assurance that they will do so. AAG's Certificate of Incorporation, Bylaws and Tax Benefit Preservation Plan include provisions that limit voting and acquisition and disposition of our equity interests and specify an exclusive forum for certain stockholder disputes. Our Certificate of Incorporation and Bylaws include significant provisions that limit voting and ownership and disposition of our equity interests as described in Part II, Item 5. Market for American Airlines Group's Common Stock, Related Stockholder Matters and Issuer Purchases of Equity Securities - "Ownership Restrictions" in our 2023 Form 10-K and AAG's Description of the Registrants' Securities Registered Pursuant to Section 12 of the Securities Exchange Act of 1934, which is filed as Exhibit 4.1 to our 2023 Form 10-K. Further restrictions are set forth in our Tax Benefit Preservation Plan, which was filed as Exhibit 4.1 to AAG's Current Report on Form 8-K filed on December 22, 2021. These restrictions may adversely affect the ability of certain holders of AAG common stock and our other equity interests to vote such interests and adversely affect the ability of persons to acquire shares of AAG common stock and our other equity interests.

◦if breached, result in an event of default under our other indebtedness. In addition, during the COVID-19 pandemic we were required to obtain a significant amount of additional financing from a variety of sources and we cannot guarantee that we will not need to obtain additional financing in the future. Such financing may include the issuance of additional unsecured or secured debt securities, equity securities and equity-linked securities as well as additional bilateral and syndicated secured and/or unsecured credit facilities, among other items. There can be no assurance as to the timing of any such financing transactions, which may be in the near term, or that we will be able to obtain such additional financing on favorable terms, or at all. Any such actions may be material in nature, could result in the incurrence and issuance of significant additional indebtedness or equity and could impose significant covenants and restrictions to which we are not currently subject. Moreover, as a result of the financing activities we undertook in response to the COVID-19 pandemic, the number of financings with respect to which such covenants and provisions apply has increased, thereby subjecting us to more substantial risk of cross-default and cross-acceleration in the event of breach, and additional covenants and provisions could become binding on us should we seek additional liquidity in the future. The obligations discussed above, including those imposed as a result of any additional financings we may undertake, could also impact our ability to obtain additional financing, if needed, and our flexibility in the conduct of our business, and could materially adversely affect our liquidity, results of operations and financial condition. Further, a substantial amount of our long-term indebtedness bears interest at floating interest rates, which tend to fluctuate based on general short-term interest rates, rates set by the U.S. Federal Reserve and other central banks, the supply of and demand for credit in treasury repurchase or other markets and general economic conditions. We have not hedged our interest rate exposure with respect to our floating rate debt. Accordingly, our interest expense for any particular period will fluctuate based on the relevant benchmark rate and other variable interest rates. In 2022 and 2023, in response to rising inflation which coincided with a rapid rebound of economic activity as governments lifted restrictions and economies reopened following the COVID-19 pandemic, central banks around the world-including the U.S. Federal Reserve, the European Central Bank and the Bank of England-undertook a cycle of raising interest rates, which has consequently increased the interest we pay on our floating-rate indebtedness. To the extent the interest rates applicable to our floating rate debt remain elevated or continue to increase, our interest expense will increase, in which event we may have difficulties making interest payments and funding our other fixed costs, and our available cash flow for general corporate requirements may be adversely affected. We have significant pension and other postretirement benefit funding obligations, which may adversely affect our liquidity, results of operations and financial condition. Our pension funding obligations are significant. The amount of our pension funding obligations will depend on the performance of investments held in trust by the pension plans, interest rates for determining liabilities and actuarial experience. We also have significant obligations for retiree medical and other postretirement benefits. Additionally, we participate in the IAM National Pension Fund (the IAM Pension Fund). The funding status of the IAM Pension Fund is subject to the risk that other employers may not meet their obligations, which under certain circumstances could cause our obligations to increase. On March 29, 2019, the actuary for the IAM Pension Fund certified that the fund was in "endangered" status despite reporting a funded status of over 80%. Additionally, the IAM Pension Fund's Board voluntarily elected to enter into "critical" status on April 17, 2019. Upon entry into critical status, the IAM Pension Fund was required by law to adopt a rehabilitation plan aimed at restoring the financial health of the pension plan and did so on April 17, 2019 (the Rehabilitation Plan). Under the Rehabilitation Plan, American was subject to an immaterial contribution surcharge, which ceased to apply on June 14, 2019 upon American's mandatory adoption of a contribution schedule under the Rehabilitation Plan. The contribution schedule requires 2.5% annual increases to its contribution rate. This contribution schedule will remain in effect through the earlier of December 31, 2031 or the date the IAM Pension Fund emerges from critical status. Furthermore, if we were to withdraw from the IAM Pension Fund, if the IAM Pension Fund were to terminate, or if the IAM Pension Fund were to undergo a mass withdrawal, we could be subject to liability as imposed by law.

If our financial condition worsens, provisions in our credit card processing and other commercial agreements may adversely affect our liquidity. We have agreements with companies that process customer credit card transactions for the sale of air travel and other services. These agreements allow these credit card processing companies, under certain conditions (including, with respect to certain agreements, our failure to maintain certain levels of liquidity), to hold an amount of our cash (referred to as a holdback) equal to some or all of the advance ticket sales that have been processed by that credit card processor, but for which we have not yet provided the air transportation. Additionally, such credit card processing companies may require cash or other collateral reserves to be established. These credit card processing companies are not currently entitled to maintain any holdbacks pursuant to these requirements. These holdback requirements can be implemented at the discretion of the credit card processing companies upon the occurrence of specific events, including material adverse changes in our financial condition or the triggering of a liquidity covenant. The imposition of holdback requirements, up to and including 100% of relevant advanced ticket sales, would materially reduce our liquidity. Likewise, other of our commercial agreements contain provisions that allow counterparties to impose less-favorable terms, including the acceleration of amounts due, in the event of material adverse changes in our financial condition. For example, we maintain certain letters of credit as well as insurance- and surety-related agreements under which counterparties may require collateral, including cash collateral. The loss of key personnel upon whom we depend to operate our business or the inability to attract, develop and retain additional qualified personnel could adversely affect our business. We believe that our future success will depend in large part on our ability to attract, develop and retain highly qualified management, technical and other personnel. We may not be successful in attracting, developing or retaining key personnel or other highly qualified personnel. In addition, competition for skilled personnel has intensified and may continue to intensify if overall industry capacity continues to increase and/or we were to incur attrition at levels higher than 60 we have historically. Any inability to attract, develop and retain significant numbers of qualified management and other personnel would have a material adverse effect on our business, results of operations and financial condition. Our business has been and will continue to be materially affected by many changing economic, geopolitical, commercial, regulatory and other conditions beyond our control, including global events that affect travel behavior, and our results of operations could be volatile and fluctuate materially due to changes in such conditions. Our business, results of operations and financial condition have been and will continue to be affected by many changing economic, geopolitical, commercial, regulatory and other conditions beyond our control, including, among others: •actual or potential changes in international, national, regional and local economic, business and financial conditions, including recession, inflation and higher interest rates; •the occurrence of wars, conflicts, terrorist attacks and geopolitical instability; •changes in consumer preferences, perceptions, spending patterns and demographic trends; •changes in the competitive environment due to industry consolidation, changes in airline alliance affiliations and other factors; •delays in scheduled aircraft deliveries, unexpected grounding of aircraft or aircraft engines whether by regulators or by us, or other loss of anticipated fleet capacity, and failure of new aircraft to receive regulatory approval, be produced or otherwise perform as and when expected; •actual or potential disruptions to the U.S. National Airspace System (the ATC system); •increases in costs of safety, security and environmental measures; •increases in costs related to meeting our climate goals or obligations, including in respect of the costs to be incurred to migrate to increased use of sustainable aviation fuel (SAF) in lieu of conventional aviation fuel;

•outbreaks of diseases or other public health or safety concerns that affect travel behavior, such as occurred during the COVID-19 pandemic; and •weather and natural disasters, including increases in frequency, severity or duration of such disasters, and related costs caused by more severe weather due to climate change. In particular, the COVID-19 pandemic, along with the measures governments and private organizations worldwide implemented in an attempt to contain its spread, resulted in significant volatility in demand for air travel, which adversely affected our business, operations and financial condition to an unprecedented extent and for a prolonged period. Measures implemented during the COVID-19 pandemic-such as travel restrictions, including testing regimes, "stay at home" and quarantine orders, limitations on public gatherings, cancellation of public events and many others-initially resulted in a precipitous decline in demand for both domestic and international business and leisure travel. In response to this material deterioration in demand, we took a number of aggressive actions to ameliorate the impacts to our business, operations and financial condition. A potential resurgence of COVID-19, or an outbreak of another contagious disease, such as has occurred in the past with the Ebola virus, Middle East Respiratory Syndrome, Severe Acute Respiratory Syndrome, H1N1 influenza virus, avian flu, Zika virus or any other similar illness, if it were to become associated with air travel or persist for an extended period, could materially affect the airline industry and us by reducing revenues and adversely impacting our operations and passengers' travel behavior. There can be no assurance that any mitigating actions we take in response will be sufficient to avert a deterioration in our business, financial condition and results of operations. As a result of these or other conditions beyond our control, our results of operations could be volatile and subject to rapid and unexpected change. In addition, due to generally weaker demand for air travel during the winter, our revenues in the first and fourth quarters of the year could be weaker than revenues in the second and third quarters of the year. 61 Additionally, the COVID-19 pandemic necessitated changes in business practices which may persist. For example, businesses and other travelers may continue to forego air travel in favor of remote or flexible working policies and communication alternatives such as videoconferencing. In addition, businesses may seek to reduce travel costs by requiring the purchase of less expensive tickets, thereby potentially impacting our average revenue per available seat mile.

The airline industry is intensely competitive and dynamic. Our competitors include other major domestic airlines and foreign, regional and new entrant airlines, as well as joint ventures formed by some of these airlines, many of which have greater financial or other resources and/or lower cost structures than ours, as well as other forms of transportation, such as rail and private automobiles or alternatives to commuting or business travel including remote or flexible working policies and communication alternatives such as videoconferencing. In many of our markets, we compete with at least one low-cost carrier (including so-called ultra-low-cost carriers). Our revenues are sensitive to the actions of other carriers in many areas, including pricing, scheduling, capacity, fees (including cancellation, change and baggage fees), amenities, loyalty benefits and promotions, which can have a substantial adverse impact not only on our revenues, but on overall industry revenues. These factors may become even more significant in periods when the industry experiences large losses (such as occurred during the COVID-19 pandemic), as airlines under financial stress, or in bankruptcy, may institute pricing or fee structures intended to attract more customers to achieve near-term survival at the expense of long-term viability. Low-cost carriers (including so-called ultra-low-cost carriers) have a profound impact on industry revenues. Using the advantage of low unit costs, these carriers offer lower fares in order to shift demand from larger, more established airlines, and represent significant competitors, particularly for customers who fly infrequently or are price sensitive and therefore tend not to be loyal to any one particular carrier. Many of these carriers, including several that have recently commenced operations, have announced growth strategies including commitments to acquire significant numbers of new aircraft for delivery in the next few years. These low-cost carriers are attempting to continue to increase their market share through growth and consolidation, and are expected to continue to have an impact on our revenues and overall performance. We and several other large network carriers have implemented "Basic Economy" fares designed to more effectively compete against low-cost carriers, but we cannot predict whether these initiatives will be successful. While historically these carriers have provided competition in domestic markets, we have recently experienced new competition from low-cost carriers on international routes, including low-cost airlines executing international long-haul expansion strategies, a trend likely to continue, in particular with the planned introduction of long-range narrowbody aircraft in coming years. Additionally, other carriers focused on premium passenger travel are attempting to implement growth strategies. The actions of existing or future carriers, including those described above, could have a material adverse effect on our operations and financial performance. In certain instances, other air carriers are attempting to operate scheduled service with a business model that relies on the Federal Aviation Administration (FAA) Part 135, a regulatory environment that is generally less stringent than the rules applicable to our airline and similar airlines that operate under FAA Part 121 and which provides those airlines certain competitive advantages that Part 121 airlines cannot replicate. We have objected to the United States Department of Transportation (DOT) and the Transportation Security Administration (TSA) that the less stringent Part 135 rules were never intended as a basis for scheduled passenger service and that business model should not be permissible, and the agencies' review is ongoing. A DOT or TSA decision to allow scheduled passenger service in any form under Part 135 and the actions of existing or future carriers using that business model, including those described above, could adversely impact our business, financial condition and results of operations. We provide air travel internationally, directly as well as through joint businesses, strategic alliances, codeshare and similar arrangements to which we are a party. While our network is comprehensive, compared to some of our key global competitors, we generally have somewhat greater relative exposure to certain regions (for example, Latin America) and somewhat lower relative exposure to others (for example, Asia). Our financial performance relative to our key competitors will therefore be influenced significantly by macro-economic conditions in particular regions around the world and the relative exposure of our network to the markets in those regions, including the duration of any declines in demand for travel to specific regions as a result of health emergencies (such as during the COVID-19 pandemic), geopolitical instability or other factors, and the speed with which demand for travel to these regions returns. Our international service exposes us to foreign economies and the potential for reduced demand when any foreign country we serve suffers adverse local economic conditions or if governments restrict commercial air service to or from any of these markets. For example, the COVID-19 pandemic resulted in a precipitous and prolonged decline in demand for air travel, in particular international travel, in part as a result of the imposition by the U.S. and foreign governments of 62

restrictions on travel from certain regions. In addition, open skies agreements, which are now in place with a substantial number of countries around the world, provide international airlines with open access to U.S. markets, potentially subjecting us to increased competition on our international routes. See also "Our business is subject to extensive government regulation, which may result in increases in our costs, disruptions to our operations, limits on our operating flexibility, reductions in the demand for air travel, and competitive disadvantages." To the extent alliances formed by our competitors can undertake activities that are not available to us, including as to regulatory approvals, access slots, gates and routes and other matters, our ability to effectively compete may be hindered. Our ability to attract and retain customers is dependent upon, among other things, our ability to offer our customers convenient access to desired markets. Our business could be adversely affected if we are unable to maintain or obtain alliance and marketing relationships with other air carriers in desired markets. American has established a transatlantic joint business with British Airways, Aer Lingus, Iberia and Finnair, a transpacific joint business with Japan Airlines and a joint business relating to Australia and New Zealand with Qantas. We have also established a strategic alliance with Alaska Airlines relating to certain routes on the West Coast of the United States and a strategic alliance relating to the Middle East with Qatar Airways. In July 2010, in connection with a regulatory review related to our transatlantic joint business, we provided certain commitments to the European Commission (EC) regarding, among other things, the availability of take-off and landing slots at London Heathrow (LHR) or London Gatwick airports. The commitments accepted by the EC were binding for 10 years. In anticipation of both the exit of the United Kingdom (UK) from the European Union (EU), commonly referred to as Brexit, and the expiry of the EC commitments in July 2020, the United Kingdom Competition and Markets Authority (CMA), in October 2018, opened an investigation into the transatlantic joint business. In September 2020 and April 2022, the CMA adopted interim measures that effectively extend the EC commitments until March 2026 in light of the uncertainty and other impacts resulting from the COVID-19 pandemic. The CMA restarted its investigation in September 2023 after a pause related to the COVID-19 pandemic and plans to complete the investigation before the scheduled expiration of the interim measures in March 2026. We continue to cooperate fully with the CMA. The foregoing arrangements are important aspects of our international network and we are dependent on the performance and continued cooperation of the other airlines party to those arrangements. On May 19, 2023, the U.S. District Court for the District of Massachusetts issued an order permanently enjoining American and JetBlue from continuing and further implementing the Northeast Alliance arrangement (NEA). In June 2023, JetBlue delivered a notice of termination of the NEA, effective July 29, 2023, and the carriers have commenced wind-down activities to accommodate mutual customers. American has appealed the District Court's decision to the Court of Appeals for the First Circuit; such appeal remains pending. Separately, in December 2022, two putative class action lawsuits were filed in the U.S. District Court for the Eastern District of New York alleging that American and JetBlue violated U.S. antitrust law in connection with the previously disclosed NEA. In February 2023, private party plaintiffs filed two additional putative class action antitrust complaints against American and JetBlue in the U.S. District Court for the District of Massachusetts and the U.S. District Court for the Eastern District of New York, respectively. All cases have since been consolidated in the U.S. District Court for the Eastern District of New York. American, together with JetBlue, filed a motion to dismiss on September 21, 2023, which remains pending. We believe these complaints are without merit and are defending against them vigorously. No assurances can be given as to any benefits that we may derive from any of the foregoing arrangements or any other arrangements that may ultimately be implemented, or whether regulators will, or if granted continue to, approve or impose material conditions on our business activities. Other mergers and other forms of airline partnerships, including regulatory approvals such as antitrust immunity grants, may take place and may not involve us as a participant, or could result in unforeseen impacts on the industry generally and our company in particular. Depending on which carriers combine or integrate and which assets, if any, are sold or otherwise transferred to other carriers in connection with any such transactions, our competitive position relative to the post-transaction carriers or other carriers that acquire such assets could be harmed. In addition, as carriers combine through traditional mergers or integrate their operations through other arrangements, their route networks will grow, and that growth will result in greater overlap with our network, which in turn could decrease our overall market share and revenues. Such combination or collaboration is not limited to the U.S., but could include further transactions among international carriers in Europe and elsewhere that result in broader networks offered by rival airlines.

to hire or retain skilled personnel, including in particular pilots and mechanics, and other risk factors, such as an out-of-court or bankruptcy restructuring of any of our regional operators. Several of these third-party regional operators provide significant regional capacity that we would be unable to replace in a short period of time should that operator fail to perform its obligations to us. Disruptions to capital markets, shortages of pilots, mechanics and other skilled personnel and adverse economic conditions in general have subjected certain of these third-party regional operators to significant financial pressures, which have in the past and may in the future lead to bankruptcies among these operators. In particular, the severe decline in demand for air travel resulting from the COVID-19 pandemic and related governmental restrictions on travel materially impacted demand for services provided by our regional carriers and, as a result, we temporarily significantly reduced our regional capacity. Further, as airlines restored capacity in line with increased demand for air travel following the height of the COVID-19 pandemic, these third-party operators experienced difficulties in recruiting and retaining sufficient personnel to operate significantly increased schedules, and have in some instances been required to offer significant increases in pay and other benefits to recruit and retain pilots and other personnel. Periods of volatility in travel demand have the potential to adversely affect our regional operators, some of whom may experience significant financial stress, declare bankruptcy or otherwise cease to operate. We may also experience disruption to our regional operations or incur financial damages if we terminate the capacity purchase agreement with one or more of our current operators or transition the services to another provider. Any significant disruption to our regional operations would have a material adverse effect on our business, results of operations and financial condition. In addition, our reliance upon others to provide essential services on our behalf in our operations may result in our relative inability to control the efficiency and timeliness of contract services. We have entered into agreements with contractors to provide various facilities and services required for our operations, including distribution and sale of airline seat inventory, reservations, provision of information technology and services, regional operations, aircraft maintenance, fueling, catering, ground services and facilities and baggage handling. Similar agreements may be entered into in any new markets we decide to serve. These agreements are generally subject to termination after notice by the third-party service provider. We are also at risk should one of these service providers cease operations, and there is no guarantee that we could replace these providers on a timely basis with comparably priced providers, or at all. These third parties have faced challenges retaining and recruiting people with the appropriate skills to meet our requirements. We rely on the operation of complex supply chains and a large number of third parties for the procurement and fulfillment of parts, components, consumable or disposable goods and other products and services essential to our business. The COVID-19 pandemic also caused significant disruption in global supply chains and staffing shortages, which affected and, if there is a resurgence, or similar event in the future, may affect the availability and timely delivery and fulfillment of many goods, including certain of those that we purchase directly or which are required by third parties to perform contracted services for us. Following a faster than expected return of demand for air travel as COVID-19 cases declined worldwide and governments lifted travel restrictions, suppliers and many of the airports we serve experienced acute shortages of personnel, resulting in increased delays, cancellations and, in certain cases, restrictions on passenger numbers or the number of flights to or from certain airports. We cannot guarantee that, as a result of ongoing or future supply chain disruptions or staffing shortages, we, our third-party partners, or the airports we serve will be able to timely source all of the products and services we require in the course of our business, or that we will be successful in procuring suitable alternatives. Any material problems with the adequacy, efficiency and timeliness of contract services, resulting from financial hardships, personnel shortages or otherwise, could have a material adverse effect on our business, results of operations and financial condition.

Union disputes, employee strikes and other labor-related disruptions may adversely affect our operations and financial performance. Relations between air carriers and labor unions in the U.S. are governed by the Railway Labor Act (RLA). Under the RLA, collective bargaining agreements (CBAs) generally contain "amendable dates" rather than expiration dates, and the RLA requires that a carrier maintain the existing terms and conditions of employment following the amendable date through a multi-stage and usually lengthy series of bargaining processes overseen by the National Mediation Board (NMB). As of December 31, 2023, approximately 87% of our employees were represented for collective bargaining purposes by labor unions, and 34% were covered by CBAs that are currently amendable or that will become amendable within one year. For the dates that the CBAs with our major work groups become amendable under the RLA, see "Labor Relations" under Part I, Item 1. Business - "Sustainability - Our People" in our 2023 Form 10-K. In the case of a CBA that is amendable under the RLA, if no agreement is reached during direct negotiations between the parties, either party may request that the NMB appoint a federal mediator. The RLA prescribes no timetable for the direct negotiation and mediation processes, and it is not unusual for those processes to last for many months or even several years. If no agreement is reached in mediation, the NMB in its discretion may declare that an impasse exists and proffer binding arbitration to the parties. Either party may decline to submit to arbitration, and if arbitration is rejected by either party, a 30-day "cooling off" period commences. During or after that period, a Presidential Emergency Board (PEB) may be established, which examines the parties' positions and recommends a solution. The PEB process lasts for 30 days and is followed by another 30-day "cooling off" period. At the end of this "cooling off" period, unless an agreement is reached or action is taken by Congress, the labor organization may exercise "self-help," such as a strike, which could materially adversely affect our business, results of operations and financial condition. None of the unions representing our employees presently may lawfully engage in concerted slowdowns or refusals to work, such as strikes, sick-outs or other similar activity, against us. Nonetheless, there is a risk that employees, either with or without union involvement, could engage in one or more concerted refusals to work that could individually or collectively harm the operation of our airline and impair our financial performance. Additionally, some of our unions have brought and may continue to bring grievances to binding arbitration, including those related to wages. If successful, there is a risk these arbitral avenues could result in material additional costs that we did not anticipate. Personnel shortages, in particular for pilots, and general wage inflation have impacted and are expected to continue to impact our labor costs. In July 2023, we reached a tentative agreement with the union representing our mainline pilots, which was subsequently ratified by the pilots in August 2023. The new agreement, which became effective in the third quarter of 2023, includes significant increases in pilot pay and benefits, in line with agreements recently concluded by our large network competitors with their pilots' unions. We remain in negotiations for other new labor agreements, including our mainline flight attendants, and anticipate that any new contracts we agree to with our labor groups will include material increases in salaries and other benefits, which will significantly increase our labor expense. If we encounter problems with any of our third-party regional operators or third-party service providers, our operations could be adversely affected by a resulting decline in revenue or negative public perception about our services. A significant portion of our regional operations are conducted by third-party operators on our behalf and are provided for under capacity purchase agreements. Due to our reliance on third parties to provide these essential services, we are subject to the risk of disruptions to their operations, which has in the past and may in the future result from many of the same risk factors disclosed in this report, such as the impact of adverse economic conditions, the inability of third parties 64

Any damage to our reputation or brand image could adversely affect our business or financial results. Maintaining a good reputation globally is critical to our business. Our reputation or brand image could be adversely impacted by, among other things, any failure to maintain high ethical, social and environmental sustainability practices for all of our operations and activities, our impact on the environment, public pressure from investors or policy groups to change our policies, such as movements to institute a "living wage," customer perceptions of our advertising campaigns, sponsorship arrangements or marketing programs, customer perceptions of our use of social media, customer concerns in the nature of "greenwashing" allegations that may surround any of our advertising campaigns, marketing programs or commercial offerings related to our sustainability initiatives, or customer perceptions of statements made by us, our employees and executives, agents or other third parties. In addition, we operate in a highly visible industry that has significant exposure to social media. Negative publicity, including as a result of misconduct by our customers, vendors or employees, can spread rapidly through social media. Should we not respond in a timely and appropriate manner to address negative publicity, our brand and reputation may be significantly harmed. Damage to our reputation or brand image or loss of customer confidence in our services could adversely affect our business and financial results, as well as require additional resources to rebuild our reputation. 65 Moreover, an outbreak and spread of an infectious disease could adversely impact consumer perceptions of the health and safety of travel, and in particular airline travel, such as occurred during the COVID-19 pandemic. Actual or perceived risk of infection on our flights could have a material adverse effect on the public's perception of us and may harm our reputation and business. We have in the past, and may in the future be required to take extensive measures to reassure our team members and the traveling public of the safety of air travel, and we could incur significant costs implementing safety, hygiene-related or other actions to limit the actual or perceived threat of infection among our employees and passengers. However, we cannot assure that any actions we might take in response to an infectious disease outbreak will be sufficient to restore the confidence of consumers in the safety of air travel. In addition, as a result of mask mandates and other mitigating measures that airports and carriers were required by law to implement to limit the spread of COVID-19, we experienced an increase in the incidence of aggressive customer behavior and physical confrontation on our flights, certain of which resulted in injuries to our personnel. While the rate of these incidents has declined following the lifting of mask mandates and other COVID-19 measures, if our employees feel unsafe or believe that we are not doing enough to prevent and prosecute such incidents, we could experience higher rates of employee absence or attrition and we may suffer reputational harm which could make it more difficult to attract and retain employees, and which could in turn negatively affect our business, financial condition and results of operations. We are at risk of losses and adverse publicity stemming from any public incident involving our company, our people or our brand, including any accident or other public incident involving our personnel or aircraft, or the personnel or aircraft of our regional, codeshare or joint business operators. We are at risk of adverse publicity stemming from any public incident involving our company, our people or our brand, particularly given the ease with which individuals can now capture and rapidly disseminate information via social media. Such an incident could involve the actual or alleged behavior of any of our employees, contractors or passengers. Further, if our personnel, one of our aircraft, a type of aircraft in our fleet, or personnel of, or an aircraft that is operated under our brand by, one of our regional operators or an airline with which we have a marketing alliance, joint business or codeshare relationship, were to be involved in a public incident, accident, catastrophe or regulatory enforcement action, we could be exposed to significant reputational harm and potential legal liability. The insurance we carry may be inapplicable or inadequate to cover any such incident, accident, catastrophe or action. In the event that our insurance is inapplicable or inadequate, we may be forced to bear substantial losses from an incident or accident. In addition, any such incident, accident, catastrophe or action involving our personnel, one of our aircraft (or personnel and aircraft of our regional operators and our codeshare partners), or a type of aircraft in our fleet could create an adverse public perception, which could harm our reputation, result in air travelers being reluctant to fly on our aircraft or those of our regional operators or codeshare partners, and adversely impact our business, results of operations and financial condition. Changes to our business model that are designed to increase revenues and reduce costs may not be successful and may cause operational difficulties or decreased demand.

We have in the past instituted, and intend to institute in the future, changes to our business model designed to increase revenues and offset costs. These measures include further segmentation of the classes of service we offer, such as Premium Economy service and Basic Economy service, enhancements to our AAdvantage program, charging separately for services that had previously been included within the price of a ticket, changes to our practices and contracts with providers of distribution systems to provide additional content flexibility, commercial practices related to ticket distribution channels, including efforts by us to migrate an increasing portion of our customers to our modern, direct distribution channels in lieu of third party channels, changing (whether it be increasing, decreasing or eliminating) other pre-existing fees, reconfiguration of our aircraft cabins, and efforts to optimize our network including by focusing growth on a limited number of large hubs and entering into agreements with other airlines. For example, in 2020, we eliminated change fees for most domestic and international tickets, which has reduced our change fee revenue, a trend which is expected to continue assuming this policy remains in place. In addition, as previously reported, during the second quarter of 2024 we concluded that certain changes to our distribution strategy contributed to softness in customer bookings relative to our expectations and we reversed many of these measures late in the quarter. We may introduce additional initiatives in the future; however, as time goes on, we expect that it will be more difficult to identify and implement additional initiatives. We cannot assure that these measures or any future initiatives will be successful in increasing our revenues or offsetting our costs. Additionally, the implementation of these initiatives may create logistical challenges that could harm the operational performance of our airline or result in decreased demand. Also, our implementation of any new or increased fees might result in adverse brand perceptions, reputational harm or regulatory scrutiny, and could reduce the demand for air travel on our airline or across the industry in general, particularly if weakened economic conditions make our customers more sensitive to increased travel costs or provide a significant competitive advantage to other carriers that determine not to institute similar charges. 66 Our intellectual property rights, particularly our branding rights, are valuable, and any inability to protect them may adversely affect our business and financial results. We consider our intellectual property rights, particularly our branding rights such as our trademarks applicable to our airline and AAdvantage program, to be a significant and valuable aspect of our business. We protect our intellectual property rights through a combination of trademark, copyright and other forms of legal protection, contractual agreements and policing of third-party misuses of our intellectual property. Our failure to obtain or adequately protect our intellectual property or any change in law that lessens or removes the current legal protections of our intellectual property may diminish our competitiveness and adversely affect our business and financial results. Any litigation or disputes regarding intellectual property may be costly and time-consuming and may divert the attention of our management and key personnel from our business operations, either of which may adversely affect our business and financial results. In addition, we have used certain of our branding and AAdvantage program intellectual property as collateral for various financings (including the AAdvantage Financing), which contain covenants that impose restrictions on the use of such intellectual property and, in the case of the AAdvantage Financing, on certain amendments or changes to our AAdvantage program. These covenants may have an adverse effect on our ability to use such intellectual property.
