Basis of Presentation

Basis of Presentation	3 Months Ended

Basis of Presentation	1. 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 On December 9, 2013, a subsidiary of AMR Corporation (AMR) merged with and into US Airways Group, Inc. (US Airways Group), a Delaware corporation, which survived as a wholly-owned subsidiary of AAG, and AAG emerged from Chapter 11 (the Merger). Upon closing of the Merger and emergence from Chapter 11, AMR changed its name to American Airlines Group Inc. On December 30, 2015, in order to simplify AAG’s internal corporate structure, US Airways, Inc. (US Airways), a wholly-owned subsidiary of US Airways Group, merged with and into American, with American as the surviving corporation. 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, valuation allowance for deferred tax assets, as well as pensions and retiree medical and other postretirement benefits. Certain prior period amounts have been reclassified to conform to the current year presentation. Recent Accounting Pronouncements Revenue In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, 2014-09 We are still in the process of evaluating how the adoption of the new revenue standard will impact our condensed consolidated financial statements. We currently expect that the new revenue standard will materially impact our liability for outstanding mileage credits earned by AAdvantage loyalty program members when flying on American. We currently use the incremental cost method to account for this portion of our loyalty program liability, which values these mileage credits based on the estimated incremental cost of carrying one additional passenger. The new revenue standard will require us to change our policy and apply a relative selling price approach whereby a portion of each passenger ticket sale attributable to mileage credits earned will be deferred and recognized in passenger revenue upon future mileage redemption. The carrying value of the earned mileage credits recognized in loyalty program liability is expected to be materially greater under the relative selling price approach than the value attributed to these mileage credits under the incremental cost method. The new revenue standard will also require us to reclassify certain ancillary fees to passenger revenue, which are currently included within other operating revenue.

Share Repurchase Programs and Dividends Since July 2014, our Board of Directors has approved six share repurchase programs aggregating $11.0 billion of authority. As of March 31, 2017, $1.5 billion remained unused under a repurchase program that expires on December 31, 2018. Share repurchases under our share repurchase programs may be made through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades or accelerated share repurchase transactions. Any such repurchases will be made from time to time subject to market and economic conditions, applicable legal requirements and other relevant factors. Our share repurchase programs do not obligate us to repurchase any specific number of shares and may be suspended at any time at our discretion. During the three months ended March 31, 2017, we repurchased 11.7 million shares of AAG common stock for $512 million at a weighted average cost per share of $43.81. Since the inception of our share repurchase programs in July 2014, we have repurchased 240.0 million shares of AAG common stock for $9.5 billion at a weighted average cost per share of $39.62.

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 On December 9, 2013, a subsidiary of AMR Corporation (AMR) merged with and into US Airways Group, Inc. (US Airways Group), a Delaware corporation, which survived as a wholly-owned subsidiary of AAG, and AAG emerged from Chapter 11 (the Merger). Upon closing of the Merger and emergence from Chapter 11, AMR changed its name to American Airlines Group Inc. On December 30, 2015, in order to simplify AAG’s internal corporate structure, US Airways, Inc. (US Airways), a wholly-owned subsidiary of US Airways Group, merged with and into American, with American as the surviving corporation. 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, valuation allowance for deferred tax assets, as well as pensions and retiree medical and other postretirement benefits. Certain prior period amounts have been reclassified to conform to the current year presentation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Revenue In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, 2014-09 We are still in the process of evaluating how the adoption of the new revenue standard will impact our condensed consolidated financial statements. We currently expect that the new revenue standard will materially impact our liability for outstanding mileage credits earned by AAdvantage loyalty program members when flying on American. We currently use the incremental cost method to account for this portion of our loyalty program liability, which values these mileage credits based on the estimated incremental cost of carrying one additional passenger. The new revenue standard will require us to change our policy and apply a relative selling price approach whereby a portion of each passenger ticket sale attributable to mileage credits earned will be deferred and recognized in passenger revenue upon future mileage redemption. The carrying value of the earned mileage credits recognized in loyalty program liability is expected to be materially greater under the relative selling price approach than the value attributed to these mileage credits under the incremental cost method. The new revenue standard will also require us to reclassify certain ancillary fees to passenger revenue, which are currently included within other operating revenue.

Recent Accounting Pronouncements	Recent Accounting Pronouncements Revenue In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, 2014-09 American is still in the process of evaluating how the adoption of the new revenue standard will impact its condensed consolidated financial statements. American currently expects that the new revenue standard will materially impact its liability for outstanding mileage credits earned by AAdvantage loyalty program members when flying on American. American currently uses the incremental cost method to account for this portion of its loyalty program liability, which values these mileage credits based on the estimated incremental cost of carrying one additional passenger. The new revenue standard will require American to change its policy and apply a relative selling price approach whereby a portion of each passenger ticket sale attributable to mileage credits earned will be deferred and recognized in passenger revenue upon future mileage redemption. The carrying value of the earned mileage credits recognized in loyalty program liability is expected to be materially greater under the relative selling price approach than the value attributed to these mileage credits under the incremental cost method. The new revenue standard will also require American to reclassify certain ancillary fees to passenger revenue, which are currently included within other operating revenue. Leases In February 2016, the FASB issued ASU 2016-02, 2016-02 right-of-use 2016-02 on-going right-of-use Statement of Cash Flows In November 2016, the FASB issued ASU 2016-18, 2016-18 2016-18 Retirement Benefits In March 2017, the FASB issued ASU 2017-07, 2017-07 pre-tax
