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 for the year ended December 31, 2015. 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. On December 9, 2013 (the Effective Date), AMR Merger Sub, Inc. merged with and into US Airways Group, Inc. (US Airways Group) (the Merger), with US Airways Group surviving as a wholly-owned subsidiary of AAG, a Delaware corporation (formerly known as AMR Corporation or AMR) following the Merger. On December 30, 2015, in order to simplify our internal corporate structure and as part of the integration efforts following the business combination of AAG and US Airways Group, AAG caused US Airways Group to be merged with and into AAG, with AAG as the surviving corporation, and, immediately thereafter, US Airways, Inc. (US Airways), a Delaware corporation and wholly-owned subsidiary of US Airways Group, merged with and into American, with American as the surviving corporation. As a result of the merger of US Airways and American, US Airways transferred all of its assets, liabilities and off-balance sheet commitments to American. For financial reporting purposes, this transaction constituted a transfer of assets between entities under common control and was accounted for at historical cost. 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 pensions, retiree medical, and other postretirement benefits. *Recent Accounting Pronouncements* In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 completes the joint effort by the FASB and International Accounting Standards Board (IASB) to improve financial reporting by creating common revenue recognition guidance for GAAP and International Financial Reporting Standards (IFRS). In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net).” ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” ASU 2016-10 clarifies the implementation guidance on identifying performance obligations. These ASUs apply to all companies that enter into contracts with customers to transfer goods or services. These ASUs are effective for public entities for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before interim and annual reporting periods beginning after December 15, 2016. Entities have the choice to apply these ASUs either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying these standards at the date of initial application and not adjusting comparative information. We are currently evaluating the requirements of these standards and have not yet determined the impact on our condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet and aligns many of the underlying principles of the new lessor model with those in Accounting Standards Codification Topic 606, Revenue from Contracts with Customers. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-02 and have not yet determined its impact on our condensed consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-09 and have not yet determined its impact on our condensed consolidated financial statements.

Basis of Presentation	1. 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, 2015. American is the principal wholly-owned subsidiary of American Airlines Group Inc. (AAG). All significant intercompany transactions have been eliminated. On December 9, 2013 (the Effective Date), AMR Merger Sub, Inc. merged with and into US Airways Group, Inc. (US Airways Group) (the Merger), with US Airways Group surviving as a wholly-owned subsidiary of AAG, a Delaware corporation (formerly known as AMR Corporation or AMR) following the Merger. On December 30, 2015, in order to simplify AAG’s internal corporate structure and as part of the integration efforts following the business combination of AAG and US Airways Group, AAG caused US Airways Group to be merged with and into AAG, with AAG as the surviving corporation, and, immediately thereafter, US Airways, Inc. (US Airways), a Delaware corporation and wholly-owned subsidiary of US Airways Group, merged with and into American, with American as the surviving corporation. As a result of the merger of US Airways and American, US Airways transferred all of its assets and liabilities, including obligations with respect to certain pass through trusts and the leases of related aircraft and engines, as well as its off-balance sheet commitments, to American. For financial reporting purposes, this transaction constituted a transfer of assets between entities under common control and is reflected in American’s condensed consolidated financial statements as though the transaction had occurred on December 9, 2013, when a subsidiary of AMR merged with and into US Airways Group, which represents the earliest date that American and US Airways were under common control. Thus, all periods presented in Part I, Item 1B of this Quarterly Report on Form 10-Q are comprised of the condensed consolidated financial data of American and US Airways. This transaction was accounted for in a manner similar to the pooling of interests method of accounting. Under this method, the carrying amount of net assets recognized in the balance sheets of each combining entity are carried forward to the balance sheet of the combined entity and no other assets or liabilities are recognized. 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.
