(“US Airways Group” or the “Company”) should be read in conjunction with the consolidated financial statements contained in US Airways Group’s Annual Report on Form 10-K for the year ended December 31, 2010. The accompanying unaudited condensed consolidated financial statements include the accounts of US Airways Group and its wholly owned subsidiaries. Wholly owned subsidiaries include US Airways, Inc.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 principal areas of judgment relate to passenger revenue recognition, impairment of long-lived and intangible assets, valuation of investments in marketable securities, the frequent traveler program and the deferred tax asset valuation allowance. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt"><b><i>Recent Accounting Pronouncements</i></b> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">In October 2009, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2009-13, “Revenue Recognition (Topic 605) — Multiple-Deliverable Revenue Arrangements.” ASU No. 2009-13 addresses the accounting for multiple-deliverable arrangements to enable vendors to account for products or services (deliverables) separately rather than as a combined unit. This guidance establishes a selling price hierarchy for determining the selling price of a deliverable, which is based on: (a) vendor-specific objective evidence; (b) third-party evidence; or (c) estimates. This guidance also eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. In addition, this guidance significantly expands required disclosures related to a vendor’s multiple-deliverable revenue arrangements. The Company’s multiple-deliverable revenue arrangements consist principally of sales of frequent flyer program mileage credits to business partners, which are comprised of two components, transportation and marketing. The Company was required to adopt and apply ASU No. 2009-13 to any new or materially modified multiple deliverable revenue arrangements entered into on or after January 1, 2011. The Company adopted ASU No. 2009-13 on January 1, 2011, and its application has had no material impact on the Company’s condensed consolidated financial statements. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> </div> falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDescription containing the entire organization, consolidation and basis of presentation of financial statements disclosure.
