New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Basis of Presentation and Recent Accounting Pronouncement	Basis of Presentation and Recent Accounting Pronouncement (a) Basis of Presentation The accompanying unaudited condensed consolidated financial statements of American Airlines Group Inc. (we, us, our and similar terms, or AAG) should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2019 . The accompanying unaudited condensed consolidated financial statements include the accounts of AAG and its wholly-owned subsidiaries. AAG’s principal subsidiary is American Airlines, Inc. (American). All significant intercompany transactions have been eliminated. Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited condensed consolidated financial statements for the interim periods presented. The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of goodwill, impairment of long-lived and intangible assets, the loyalty program, as well as pension and retiree medical and other postretirement benefits. (b) Impact of Coronavirus (COVID-19) COVID-19 has been declared a global health pandemic by the World Health Organization. COVID-19 has surfaced in nearly all regions of the world, which has driven the implementation of significant, government-imposed measures to prevent or reduce its spread, including travel restrictions, closing of borders, “shelter in place” orders and business closures . As a result, we have experienced an unprecedented decline in the demand for air travel, which has resulted in a material deterioration in our revenues. While our business performed largely as expected in January and February of 2020 , a severe reduction in air travel during March 2020 resulted in our total operating revenues decreasing nearly 20% in the first quarter of 2020 as compared to the first quarter of 2019 . While the length and severity of the reduction in demand due to COVID-19 is uncertain, we presently expect the deterioration to increase in the second quarter of 2020 and our results of operations for the remainder of 2020 to be severely impacted. We have taken aggressive actions to mitigate the effect of COVID-19 on our business including deep capacity reductions, structural changes to our fleet, cost reductions, and steps to preserve cash and improve our overall liquidity position. We remain extremely focused on taking all self-help measures available to manage our business during this unprecedented time, consistent with the terms of the financial support we have received from the U.S. Government under the Coronavirus Aid, Relief, and Economic Security (CARES) Act which, among other things, includes obligations regarding minimum air service and restrictions on involuntary workforce actions. See Note 14 for further information. Capacity Reductions We have significantly reduced our capacity (as measured by available seat miles), with April and May 2020 flying expected to decrease by approximately 80% year-over-year and June 2020 flying expected to decrease by approximately 70% year-over-year. Given the fluidity of the environment, we will continue to evaluate these targets and make further demand-driven adjustments to our capacity as needed. Fleet To better align our network with lower passenger demand, we have accelerated the retirement of Boeing 757, Boeing 767, Airbus A330-300 and Embraer 190 fleets as well as certain regional aircraft. These retirements remove complexity from our operation and bring forward cost savings and efficiencies associated with operating fewer aircraft types. See Note 13 for further information on the accounting for our fleet retirements. Due to the inherent uncertainties of the current operating environment, we will continue to evaluate our current fleet and may decide to permanently retire additional aircraft. Cost Reductions We are moving quickly to align our costs with our reduced schedule. In aggregate, we estimate that we have reduced our 2020 operating and capital expenditures by more than $12 billion . These savings have been achieved through lower fuel expense and a series of actions, including the capacity reductions and accelerated fleet retirements discussed above as well as reductions in heavy maintenance expense, the deferral of marketing expenditures, consolidation of space at airport facilities and reductions in contractor, event and training expenses. We have also suspended all non-essential hiring, paused non-contractual pay rate increases, reduced executive and board of director compensation and implemented voluntary leave and early retirement programs to reduce our labor costs consistent with our obligations under the CARES Act. In total, nearly 39,000 team members have opted for early retirement, a reduced work schedule or a partially-paid leave status . Our average estimated second quarter 2020 cash burn rate is currently expected to be approximately $70 million per day, and we presently expect this amount to decrease over time to approximately $50 million per day for the month of June 2020 as these cost-savings initiatives gain traction and assuming no material, unforecasted revenue reductions, costs or other events. Liquidity At March 31, 2020 , we had $6.8 billion in total available liquidity, consisting of $3.6 billion in unrestricted cash and short-term investments and $3.2 billion in undrawn capacity under our revolving credit facilities, of which we borrowed $2.7 billion in April 2020. During the first quarter of 2020 , we completed the following financing transactions (see Note 6 for further information): • refinanced the $1.2 billion 2014 Term Loan Facility at a lower interest rate and extended the maturity from 2021 to 2027; • raised $1.0 billion from a 364 -day senior secured delayed draw term loan credit facility; • issued $500 million in aggregate principal amount of 3.75% unsecured senior notes due 2025 and repaid $500 million of 4.625% unsecured senior notes that matured in March 2020; • raised $280 million from aircraft sale-leaseback transactions; and • raised $197 million from aircraft financings, of which $17 million was used to repay existing indebtedness. We have been approved to receive an aggregate of $5.8 billion in financial assistance to be paid in installments through the payroll support program (Payroll Support Program) under the CARES Act of which we received an initial disbursement of $2.9 billion in April 2020 (representing 50% of the current expected total). We currently anticipate receiving three additional installments from May to July 2020. As partial compensation to the U.S. Government for the provision of financial assistance under the Payroll Support Program, we expect to issue an aggregate principal amount of approximately $1.7 billion under a promissory note and warrants to purchase up to 13.7 million shares of AAG common stock (assuming the full $5.8 billion of financial assistance is received). As of the date of this report, the principal amount of this promissory note is $842 million and a warrant to purchase up to 6.7 million shares of AAG common stock has been issued. The principal amount of this promissory note will increase by an amount equal to 30% of each additional installment disbursed under the PSP Agreement, and we will issue a warrant for a number of shares of AAG common stock equal to 10% of each such increase in the principal amount of this promissory note, divided by $12.51 per share (the exercise price per share of such warrants). See Note 14 for further information on the Payroll Support Program. We also applied for a secured loan from the U.S. Department of the Treasury (Treasury) of approximately $4.75 billion under the CARES Act, which if granted will involve the issuance of additional warrants to purchase approximately 38.0 million shares of AAG common stock. As of the date of this report, the secured loan application has not been acted on. Also, we are permitted to, and will, defer payment of the employer portion of social security taxes through the end of 2020 (with 50% of the deferred amount due December 31, 2021 and the remaining 50% due December 31, 2022). This deferral is expected to provide approximately $300 million in additional liquidity during 2020 . Additionally, we have suspended our capital return program, including share repurchases and the payment of future dividends for at least the period that the restrictions imposed by the CARES Act are applicable. We continue to evaluate future financing opportunities and have engaged third-party appraisers to evaluate some of our unencumbered assets. We expect to pledge a portion of these unencumbered assets as collateral for future financings, including as part of the approximately $4.75 billion secured loan we have applied for under the CARES Act. Certain 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/or contain loan to value ratio covenants. Given the above actions and our assumptions about the future impact of COVID-19 on travel demand, which could be materially different due to the inherent uncertainties of the current operating environment, we expect to meet our cash obligations as well as remain in compliance with the debt covenants in our existing financing agreements for the next 12 months based on our current level of unrestricted cash and short-term investments, our anticipated access to liquidity (including via proceeds from financings and funds from government assistance to be provided pursuant to the CARES Act) and projected cash flows from operations . (c) Recent Accounting Pronouncement Accounting Standards Update (ASU) 2016-13: Financial Instruments – Credit Losses (Topic 326) This ASU requires the use of an expected loss model for certain types of financial instruments and requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. For trade receivables, loans and held-to-maturity debt securities, an estimate of lifetime expected credit losses is required. For available-for-sale debt securities, an allowance for credit losses will be required rather than a reduction to the carrying value of the asset. We adopted this accounting standard prospectively as of January 1, 2020, and it did not have a material impact on our condensed consolidated financial statements.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Basis of Presentation and Recent Accounting Pronouncement	Basis of Presentation and Recent Accounting Pronouncement (a) Basis of Presentation The accompanying unaudited condensed consolidated financial statements of American Airlines, Inc. (American) should be read in conjunction with the consolidated financial statements contained in American’s Annual Report on Form 10-K for the year ended December 31, 2019 . American is the principal wholly-owned subsidiary of American Airlines Group Inc. (AAG). All significant intercompany transactions have been eliminated. Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited condensed consolidated financial statements for the interim periods presented. The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of goodwill, impairment of long-lived and intangible assets, the loyalty program, as well as pension and retiree medical and other postretirement benefits. (b) Impact of Coronavirus (COVID-19) COVID-19 has been declared a global health pandemic by the World Health Organization. COVID-19 has surfaced in nearly all regions of the world, which has driven the implementation of significant, government-imposed measures to prevent or reduce its spread, including travel restrictions, closing of borders, “shelter in place” orders and business closures . As a result, American has experienced an unprecedented decline in the demand for air travel, which has resulted in a material deterioration in its revenues. While American's business performed largely as expected in January and February of 2020, a severe reduction in air travel during March 2020 resulted in its total operating revenues decreasing nearly 20% in the first quarter of 2020 as compared to the first quarter of 2019 . While the length and severity of the reduction in demand due to COVID-19 is uncertain, American presently expects the deterioration to increase in the second quarter of 2020 and its results of operations for the remainder of 2020 to be severely impacted. American has taken aggressive actions to mitigate the effect of COVID-19 on its business including deep capacity reductions, structural changes to its fleet, cost reductions, and steps to preserve cash and improve its overall liquidity position. American remains extremely focused on taking all self-help measures available to manage its business during this unprecedented time, consistent with the terms of the financial support it has received from the U.S. Government under the Coronavirus Aid, Relief, and Economic Security (CARES) Act which, among other things, includes obligations regarding minimum air service and restrictions on involuntary workforce actions. See Note 13 for further information. Capacity Reductions American has significantly reduced its capacity (as measured by available seat miles), with April and May 2020 flying expected to decrease by approximately 80% year-over-year and June 2020 flying expected to decrease by approximately 70% year-over-year. Given the fluidity of the environment, American will continue to evaluate these targets and make further demand-driven adjustments to its capacity as needed. Fleet To better align American’s network with lower passenger demand, American has accelerated the retirement of Boeing 757, Boeing 767, Airbus A330-300 and Embraer 190 fleets as well as certain regional aircraft. These retirements remove complexity from its operation and bring forward cost savings and efficiencies associated with operating fewer aircraft types. See Note 12 for further information on the accounting for American's fleet retirements. Due to the inherent uncertainties of the current operating environment, American will continue to evaluate its current fleet and may decide to permanently retire additional aircraft. Cost Reductions American is moving quickly to align its costs with its reduced schedule. In aggregate, American estimates that it has reduced its 2020 operating and capital expenditures by more than $12 billion . These savings have been achieved through lower fuel expense and a series of actions, including the capacity reductions and accelerated fleet retirements discussed above as well as reductions in heavy maintenance expense, the deferral of marketing expenditures, consolidation of space at airport facilities and reductions in contractor, event and training expenses. American has also suspended all non-essential hiring, paused non-contractual pay rate increases, reduced executive and board of director compensation and implemented voluntary leave and early retirement programs to reduce its labor costs consistent with its obligations under the CARES Act. In total, nearly 39,000 team members have opted for early retirement, a reduced work schedule or a partially-paid leave status . American's average estimated second quarter 2020 cash burn rate is currently expected to be approximately $70 million per day, and American presently expects this amount to decrease over time to approximately $50 million per day for the month of June 2020 as these cost-savings initiatives gain traction and assuming no material, unforecasted revenue reductions, costs or other events. Liquidity At March 31, 2020 , American had $6.8 billion in total available liquidity, consisting of $3.6 billion in unrestricted cash and short-term investments and $3.2 billion in undrawn capacity under its revolving credit facilities, of which American borrowed $2.7 billion in April 2020. During the first quarter of 2020 , American completed the following financing transactions (see Note 4 for further information): • refinanced the $1.2 billion 2014 Term Loan Facility at a lower interest rate and extended the maturity from 2021 to 2027; • raised $1.0 billion from a 364 -day senior secured delayed draw term loan credit facility; • raised $280 million from aircraft sale-leaseback transactions; and • raised $197 million from aircraft financings, of which $17 million was used to repay existing indebtedness. AAG and its subsidiaries have been approved to receive an aggregate of $5.8 billion in financial assistance to be paid in installments through the payroll support program (Payroll Support Program) under the CARES Act of which it received an initial disbursement of $2.9 billion in April 2020 (representing 50% of the current expected total). American and its regional affiliates currently anticipate receiving three additional installments from May to July 2020. As partial compensation to the U.S. Government for the provision of financial assistance under the Payroll Support Program, AAG and its subsidiaries expect to issue an aggregate principal amount of approximately $1.7 billion under a promissory note and warrants to purchase up to 13.7 million shares of AAG common stock (assuming the full $5.8 billion of financial assistance is received). As of the date of this report, the principal amount of this promissory note is $842 million and a warrant to purchase up to 6.7 million shares of AAG common stock has been issued. The principal amount of this promissory note will increase by an amount equal to 30% of each additional installment disbursed under the PSP Agreement, and AAG will issue a warrant for a number of shares of AAG common stock equal to 10% of each such increase in the principal amount of this promissory note, divided by $12.51 per share (the exercise price per share of such warrants). See Note 13 for further information on the Payroll Support Program. AAG and its subsidiaries also applied for a secured loan from the U.S. Department of the Treasury (Treasury) of approximately $4.75 billion under the CARES Act, which if granted will involve the issuance of additional warrants to purchase approximately 38.0 million shares of AAG common stock. As of the date of this report, the secured loan application has not been acted on. Also, American is permitted to, and will, defer payment of the employer portion of social security taxes through the end of 2020 (with 50% of the deferred amount due December 31, 2021 and the remaining 50% due December 31, 2022). This deferral is expected to provide approximately $300 million in additional liquidity during 2020 . Additionally, AAG has suspended its capital return program, including share repurchases and the payment of future dividends for at least the period that the restrictions imposed by the CARES Act are applicable . American continues to evaluate future financing opportunities and has engaged third-party appraisers to evaluate some of its unencumbered assets. American expects to pledge a portion of these unencumbered assets as collateral for future financings, including as part of the approximately $4.75 billion secured loan AAG and its subsidiaries have applied for under the CARES Act. Certain of American’s debt financing agreements contain covenants requiring it 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/or contain loan to value ratio covenants. Given the above actions and American’s assumptions about the future impact of COVID-19 on travel demand, which could be materially different due to the inherent uncertainties of the current operating environment, American expects to meet its cash obligations as well as remain in compliance with the debt covenants in its existing financing agreements for the next 12 months based on its current level of unrestricted cash and short-term investments, its anticipated access to liquidity (including via proceeds from financings and funds from government assistance to be provided pursuant to the CARES Act) and projected cash flows from operations .

The 2014 Revolving Facility remains unchanged and, as of March 31, 2020 , there were no borrowings or letters of credit outstanding thereunder. 3.75% Senior Notes In February 2020, AAG issued $500 million aggregate principal amount of 3.75% senior notes due 2025 (the 3.75% senior notes). These notes bear interest at a rate of 3.75% per annum, payable semi-annually in arrears in March and September of each year, beginning in September 2020. The 3.75% senior notes are senior unsecured obligations of AAG and are fully and unconditionally guaranteed by American. The 3.75% senior notes mature in March 2025. Delayed Draw Term Loan Credit Facility In March 2020, American and AAG entered into a Credit and Guaranty Agreement which provides for a 364 -day $1.0 billion senior secured delayed draw term loan credit facility (the Delayed Draw Term Loan Credit Facility), which will be due and payable in a single installment on the maturity date in March 2021. Borrowings under the Delayed Draw Term Loan Credit Facility bear interest at an index rate plus an applicable index margin or, at American's option, LIBOR (subject to a floor of 1.00% ) plus an applicable LIBOR margin for interest periods of one, three or six months (or, if available to all affected lenders, 12 months or a shorter period). Voluntary prepayments at par may be made by American at any time. As of March 31, 2020 , $1.0 billion in borrowings were outstanding under the Delayed Draw Term Loan Credit Facility. The proceeds of the term loans under the Delayed Draw Term Loan Credit Facility are being used for general corporate purposes. Subject to certain limitations and exceptions, the Delayed Draw Term Loan Credit Facility is secured by collateral, including certain slots, foreign gate leaseholds and route authorities (collectively, SGR) utilized by American in providing its scheduled air carrier services to and from Mexico and Central America and to London and certain cities in the European Union. The lien on Mexico and Central America SGR is a first-priority lien and the lien on London and European SGR is a second-priority lien. American has the ability to make future modifications to the collateral pledged, subject to certain restrictions. American's obligations under the Delayed Draw Term Loan Credit Facility are guaranteed by AAG. American is required to maintain a certain minimum ratio of appraised value of collateral to the outstanding term loans. The Delayed Draw Term Loan Credit Facility contains events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations may be accelerated and become due and payable immediately. The Delayed Draw Term Loan Credit Facility also includes covenants that, among other things, require AAG to maintain a minimum aggregate liquidity of not less than $2.0 billion and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur additional indebtedness, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions. Equipment Notes and Other Notes Payable Issued in 2020 In the three months ended March 31, 2020 , American entered into agreements under which it borrowed $197 million in connection with the financing or refinancing, as the case may be, of certain aircraft, of which $17 million was used to repay existing indebtedness. Debt incurred under these agreements matures in 2029 through 2032 and bears interest at variable rates (comprised of LIBOR plus an applicable margin) averaging 2.99% at March 31, 2020 .

Legal Proceedings	Legal Proceedings Chapter 11 Cases . On November 29, 2011, AMR Corporation (AMR), American, and certain of AMR’s other direct and indirect domestic subsidiaries (the Debtors) filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Southern District of New York (the Bankruptcy Court). On October 21, 2013, the Bankruptcy Court entered an order approving and confirming the Debtors’ fourth amended joint plan of reorganization (as amended, the Plan). On the Effective Date, December 9, 2013, the Debtors consummated their reorganization pursuant to the Plan and completed the acquisition of US Airways Group, Inc. by AMR (the Merger). Pursuant to rulings of the Bankruptcy Court, the Plan established the Disputed Claims Reserve to hold shares of AAG common stock reserved for issuance to disputed claimholders at the Effective Date that ultimately become holders of allowed claims. The shares of AAG common stock issued to the Disputed Claims Reserve were originally issued on December 13, 2013 and have at all times since been included in the number of shares issued and outstanding as reported from time to time in our quarterly and annual reports, including for calculating earnings per common share. As disputed claims are resolved, the claimants receive distributions of shares from the Disputed Claims Reserve. We are not required to distribute additional shares above the limits contemplated by the Plan, even if the shares remaining for distribution in the Disputed Claims Reserve are not sufficient to fully pay any additional allowed unsecured claims. If any of the reserved shares remain undistributed upon resolution of all remaining disputed claims, such shares will not be returned to us but rather will be distributed to former AMR stockholders and former convertible noteholders treated as stockholders under the Plan. In the first quarter of 2020 , 2.2 million shares of AAG common stock were distributed from the Disputed Claims Reserve. After giving effect to this distribution, as of March 31, 2020 , the Disputed Claims Reserve held 4.8 million shares of AAG common stock. Private Party Antitrust Action Related to Passenger Capacity. We, along with Delta Air Lines, Inc., Southwest Airlines Co., United Airlines, Inc. and, in the case of litigation filed in Canada, Air Canada, were named as defendants in approximately 100 putative class action lawsuits alleging unlawful agreements with respect to air passenger capacity. The U.S. lawsuits were consolidated in the Federal District Court for the District of Columbia (the DC Court). On June 15, 2018, we reached a settlement agreement with the plaintiffs in the amount of $45 million to resolve all class claims in the U.S. lawsuits. That settlement was approved by the DC Court on May 13, 2019, however three parties who objected to the settlement have appealed that decision to the United States Court of Appeals for the District of Columbia. We believe these appeals are without merit and intend to vigorously defend against them. Private Party Antitrust Action Related to the Merger . On August 6, 2013, a lawsuit captioned Carolyn Fjord, et al., v. AMR Corporation, et al., was filed in the Bankruptcy Court. The complaint named as defendants US Airways Group, Inc., US Airways, Inc., AMR and American, alleged that the effect of the Merger may be to create a monopoly in violation of Section 7 of the Clayton Antitrust Act, and sought injunctive relief and/or divestiture. On November 27, 2013, the Bankruptcy Court denied plaintiffs’ motion to preliminarily enjoin the Merger. On August 29, 2018, the Bankruptcy Court denied in part defendants' motion for summary judgment, and fully denied plaintiffs' cross-motion for summary judgment. The parties' evidentiary cases were presented before the Bankruptcy Court in a bench trial in March 2019. The parties submitted proposed findings of fact and conclusions of law and made closing arguments in April 2019, and we are awaiting the Bankruptcy Court's decision. We believe this lawsuit is without merit and intend to vigorously defend against the allegations. Pension Benefits Action. On December 11, 2018, a lawsuit captioned Torres, et al. v. American Airlines, Inc., The Employee Benefits Committee and John/Jane Does 1-5, was filed in the United States District Court for the Northern District of Texas. The plaintiffs in this lawsuit purport to represent a class consisting of all participants in and beneficiaries under any of the four American defined benefit pension plans who elected to receive an optional form of benefit other than a lump sum distribution of a participant’s vested benefit. Under the Employee Retirement Income Security Act, participants covered by defined benefit plans accrue retirement benefits in the form of a single life annuity payable upon retirement on a monthly basis until the employee’s death, and may elect certain alternative forms of benefit payments. Plaintiffs contend that the mortality tables used by American for purposes of calculations related to these alternative forms of benefits are outdated and that more recent mortality tables would have provided more generous benefits and should have been used to make those calculations. The court has denied our motion to dismiss the complaint. We believe this lawsuit is without merit and intend to vigorously defend against the allegations. General . In addition to the specifically identified legal proceedings, we and our subsidiaries are also engaged in other legal proceedings from time to time. 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. Therefore, although we will vigorously defend ourselves in each of the actions described above and such other legal proceedings, their ultimate resolution and potential financial and other impacts on us are uncertain but could be material.

Legal Proceedings	Legal Proceedings Chapter 11 Cases . On November 29, 2011, AMR Corporation (AMR), American, and certain of AMR’s other direct and indirect domestic subsidiaries (the Debtors) filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Southern District of New York (the Bankruptcy Court). On October 21, 2013, the Bankruptcy Court entered an order approving and confirming the Debtors’ fourth amended joint plan of reorganization (as amended, the Plan). On the Effective Date, December 9, 2013, the Debtors consummated their reorganization pursuant to the Plan and completed the acquisition of US Airways Group, Inc. by AMR (the Merger). Pursuant to rulings of the Bankruptcy Court, the Plan established the Disputed Claims Reserve to hold shares of AAG common stock reserved for issuance to disputed claimholders at the Effective Date that ultimately become holders of allowed claims. The shares of AAG common stock issued to the Disputed Claims Reserve were originally issued on December 13, 2013 and have at all times since been included in the number of shares issued and outstanding as reported by AAG from time to time in its quarterly and annual reports, including for calculating earnings per common share. As disputed claims are resolved, the claimants receive distributions of shares from the Disputed Claims Reserve. American is not required to distribute additional shares above the limits contemplated by the Plan, even if the shares remaining for distribution in the Disputed Claims Reserve are not sufficient to fully pay any additional allowed unsecured claims. If any of the reserved shares remain undistributed upon resolution of all remaining disputed claims, such shares will not be returned to AAG but rather will be distributed to former AMR stockholders and former convertible noteholders treated as stockholders under the Plan. In the first quarter of 2020 , 2.2 million shares of AAG common stock were distributed from the Disputed Claims Reserve. After giving effect to this distribution, as of March 31, 2020 , the Disputed Claims Reserve held 4.8 million shares of AAG common stock. Private Party Antitrust Action Related to Passenger Capacity. American, along with Delta Air Lines, Inc., Southwest Airlines Co., United Airlines, Inc. and, in the case of litigation filed in Canada, Air Canada, were named as defendants in approximately 100 putative class action lawsuits alleging unlawful agreements with respect to air passenger capacity. The U.S. lawsuits were consolidated in the Federal District Court for the District of Columbia (the DC Court). On June 15, 2018, American reached a settlement agreement with the plaintiffs in the amount of $45 million to resolve all class claims in the U.S. lawsuits. That settlement was approved by the DC Court on May 13, 2019, however three parties who objected to the settlement have appealed that decision to the United States Court of Appeals for the District of Columbia. American believes these appeals are without merit and intends to vigorously defend against them. Private Party Antitrust Action Related to the Merger . On August 6, 2013, a lawsuit captioned Carolyn Fjord, et al., v. AMR Corporation, et al., was filed in the Bankruptcy Court. The complaint named as defendants US Airways Group, Inc., US Airways, Inc., AMR and American, alleged that the effect of the Merger may be to create a monopoly in violation of Section 7 of the Clayton Antitrust Act, and sought injunctive relief and/or divestiture. On November 27, 2013, the Bankruptcy Court denied plaintiffs’ motion to preliminarily enjoin the Merger. On August 29, 2018, the Bankruptcy Court denied in part defendants' motion for summary judgment, and fully denied plaintiffs' cross-motion for summary judgment. The parties' evidentiary cases were presented before the Bankruptcy Court in a bench trial in March 2019. The parties submitted proposed findings of fact and conclusions of law and made closing arguments in April 2019, and they are awaiting the Bankruptcy Court's decision. American believes this lawsuit is without merit and intends to vigorously defend against the allegations. Pension Benefits Action. On December 11, 2018, a lawsuit captioned Torres, et al. v.

Impairment	Impairment Long-lived Assets Accounting Standards Codification (ASC) 360 - Property, Plant, and Equipment (ASC 360) requires long-lived assets to be assessed for impairment when events and circumstances indicate that the assets may be impaired. Long-lived assets consist of owned flight and ground equipment, ROU assets and definite-lived intangible assets such as certain domestic airport slots and gate leasehold rights, customer relationships and marketing agreements. As previously discussed, in the first quarter of 2020 , our operations, liquidity and stock price were significantly impacted by decreased passenger demand and U.S. government travel restrictions due to COVID-19. Additionally, we decided to retire certain mainline aircraft earlier than planned including Boeing 757, Boeing 767, Airbus A330-300 and Embraer 190 aircraft as well as regional aircraft, including certain Embraer 140 and Bombardier CRJ200 aircraft. As a result of these events and circumstances, we performed impairment tests on our long-lived assets in connection with the preparation of our financial statements. In accordance with ASC 360, an impairment of a long-lived asset or group of long-lived assets exists only when the sum of the estimated undiscounted future cash flows expected to be generated directly by the assets are less than the carrying value of the assets. We group assets principally by fleet-type when estimating future cash flows, which is generally the lowest level for which identifiable cash flows exist. Estimates of future cash flows are based on historical results adjusted to reflect management’s best estimate of future market and operating conditions, including our current fleet plan. As a result of the impairment tests performed on our long-lived assets, we determined the sum of the estimated undiscounted future cash flows exceeded the $44.6 billion carrying value for our long-lived assets except for the aircraft being retired earlier than planned as discussed above. For those aircraft and certain related spare parts, we recorded an $815 million impairment charge reflecting the difference between the carrying values of these assets and their fair values. Fair value reflects management’s best estimate including inputs from published pricing guides and bids from third parties as well as contracted sales agreements when applicable. Due to the inherent uncertainties of the current operating environment, we will continue to evaluate our current fleet and may decide to permanently retire additional aircraft. Goodwill and Indefinite-lived Intangible Assets ASC 350 - Intangibles - Goodwill and Other (ASC 350) requires goodwill and indefinite-lived intangible assets to be assessed for impairment annually or more frequently if events or circumstances indicate that the fair values of goodwill and indefinite-lived intangible assets may be lower than their carrying values. Goodwill represents the purchase price in excess of the fair value of the net assets acquired and liabilities assumed in connection with the merger with US Airways Group, Inc. We have one reporting unit. Indefinite-lived intangible assets consist of certain domestic airport slots and international slots and route authorities. In the first quarter of 2020 , we performed an interim impairment test on our goodwill and indefinite-lived intangible assets as a result of the events and circumstances previously discussed due to the impact of COVID-19 on our business. In accordance with ASC 350, for goodwill, we performed a quantitative analysis by using a market approach. Under the market approach, the fair value of the reporting unit was determined based on quoted market prices for equity and the fair value of debt as described in Note 8. The fair value exceeded the carrying value of the reporting unit, and our $4.1 billion of goodwill was not impaired. Additionally, in the first quarter of 2020 , we performed an interim qualitative impairment test on our $1.8 billion of indefinite-lived intangible assets and determined there was no material impairment. As discussed above, due to the inherent uncertainties of the current operating environment, we will continue to evaluate our goodwill and indefinite-lived intangible assets for events or circumstances that indicate that their fair values may be lower than their carrying values.

Following the April 2020 draw, American had no remaining borrowing capacity available under the 2013 Revolving Facility or the April 2016 Revolving Facility and had $110 million in remaining borrowing capacity available under the 2014 Revolving Facility. Payroll Support Program On April 20, 2020 (the PSP Closing Date), American, Envoy Air Inc. (Envoy), Piedmont Airlines, Inc. (Piedmont) and PSA Airlines, Inc. (PSA and together with American, Envoy and Piedmont, the Subsidiaries), each our wholly-owned subsidiary, entered into a Payroll Support Program Agreement (the PSP Agreement) with Treasury, with respect to the Payroll Support Program provided pursuant to the CARES Act. In connection with our entry into the PSP Agreement, on the PSP Closing Date, we also entered into a Warrant Agreement (the Warrant Agreement) with Treasury, and we issued a promissory note to Treasury (the Promissory Note), with the Subsidiaries as guarantors (the Guarantors). Payroll Support Program Agreement Pursuant to the PSP Agreement, Treasury is to provide to us financial assistance to be paid in installments (each, an Installment) expected to total in the aggregate approximately $5.8 billion . The first Installment, in the amount of approximately $2.9 billion (representing 50% of the current expected total) was disbursed by Treasury on April 21, 2020, and we currently anticipate receiving three additional Installments from May to July 2020. In connection with the Payroll Support Program, we are required to comply with the relevant provisions of the CARES Act, including the requirement that funds provided pursuant to the PSP Agreement be used exclusively for the continuation of payment of employee wages, salaries and benefits, the requirement against involuntary furloughs and reductions in employee pay rates and benefits through September 30, 2020, the requirement that certain levels of commercial air service be maintained and the provisions that prohibit the repurchase of AAG common stock, and the payment of common stock dividends through September 30, 2021, as well as those that restrict the payment of certain executive compensation until March 24, 2022. The PSP Agreement also imposes substantial reporting obligations on us and the Subsidiaries. Payroll Support Program Promissory Note As compensation to the U.S. Government for the provision of financial assistance under the PSP Agreement, we issued the Promissory Note to Treasury, which provides for our unconditional promise to pay to Treasury the initial principal sum of approximately $842 million , subject to an increase equal to 30% of the amount of each additional Installment disbursed under the PSP Agreement after the PSP Closing Date, and the guarantee of our obligations by the Guarantors. Assuming the total Installments to be paid pursuant to the PSP Agreement aggregate approximately $5.8 billion , the Promissory Note will have a total principal sum of approximately $1.7 billion . The Promissory Note bears interest on the outstanding principal amount at a rate equal to 1.00% per annum until the fifth anniversary of the PSP Closing Date and 2.00% plus an interest rate based on the secured overnight financing rate per annum or other benchmark replacement rate consistent with customary market conventions (but not to be less than 0.00% ) thereafter until the tenth anniversary of the PSP Closing Date (the Maturity Date), and interest accrued thereon will be payable in arrears on the last business day of March and September of each year, beginning on September 30, 2020. The aggregate principal amount outstanding under the Promissory Note, together with all accrued and unpaid interest thereon and all other amounts payable under the Promissory Note, will be due and payable on the Maturity Date. We may, at any time and from time to time, voluntarily prepay amounts outstanding under the Promissory Note, in whole or in part, without penalty or premium. Within 30 days of the occurrence of certain change of control triggering events, we are required to prepay the aggregate outstanding principal amount of the Promissory Note at such time, together with any accrued interest or other amounts owing under the Promissory Note at such time . The Promissory Note is our senior unsecured obligation and each guarantee of the Promissory Note is the senior unsecured obligation of each of the Guarantors, respectively . The Promissory Note contains events of default, including cross-default with respect to acceleration or failure to pay at maturity other material indebtedness. Upon the occurrence of an event of default and subject to certain grace periods, the outstanding obligations under the Promissory Note may, and in certain circumstances will automatically, be accelerated and become due and payable immediately. Payroll Support Program Warrant Agreement and Warrants As compensation to the U.S. Government for the provision of financial assistance under the PSP Agreement, and pursuant to the Warrant Agreement, we have agreed to issue warrants (each a PSP Warrant and, collectively, the PSP Warrants) to Treasury to purchase up to an aggregate of approximately 13.7 million shares (the Warrant Shares) of AAG common stock. The exercise price of the Warrant Shares is $12.51 per share (which was the closing price of AAG common stock on The Nasdaq Global Select Market on April 9, 2020) (the Exercise Price) subject to certain anti-dilution provisions provided for in the PSP Warrant. Pursuant to the Warrant Agreement, (a) on the PSP Closing Date, we issued to Treasury a PSP Warrant to purchase up to an aggregate of approximately 6.7 million shares of AAG common stock based on the terms described herein and (b) on the date of each increase of the principal amount of the Promissory Note in connection with the disbursement of an additional Installment under the PSP Agreement, we will issue to Treasury an additional PSP Warrant for a number of shares of AAG common stock equal to 10% of such increase of the principal amount of the Promissory Note, divided by the Exercise Price. Assuming the total Installments to be paid pursuant to the PSP Agreement aggregate approximately $5.8 billion , the total number of Warrant Shares issuable is approximately 13.7 million , subject to certain anti-dilution provisions, including, among others, for below market issuances and payment of dividends, provided for in the PSP Warrants. The PSP Warrant does not have any voting rights and is freely transferrable, with registration rights. Each PSP Warrant expires on the fifth anniversary of the date of issuance of such PSP Warrant. The PSP Warrants will be exercisable either through net share settlement or cash, at our option. The PSP Warrant was issued solely as compensation to the U.S. Government related to entry into the PSP Agreement. No separate proceeds (apart from the financial assistance Installments described above) were received upon issuance of the PSP Warrant or will be received upon exercise thereof.

The accompanying unaudited condensed consolidated financial statements include the accounts of AAG and its wholly-owned subsidiaries. AAG’s principal subsidiary is American Airlines, Inc. (American). All significant intercompany transactions have been eliminated. Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited condensed consolidated financial statements for the interim periods presented. The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of goodwill, impairment of long-lived and intangible assets, the loyalty program, as well as pension and retiree medical and other postretirement benefits.
Recent Accounting Pronouncements	Recent Accounting Pronouncement Accounting Standards Update (ASU) 2016-13: Financial Instruments – Credit Losses (Topic 326) This ASU requires the use of an expected loss model for certain types of financial instruments and requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. For trade receivables, loans and held-to-maturity debt securities, an estimate of lifetime expected credit losses is required. For available-for-sale debt securities, an allowance for credit losses will be required rather than a reduction to the carrying value of the asset. We adopted this accounting standard prospectively as of January 1, 2020, and it did not have a material impact on our condensed consolidated financial statements.
