Report of Independent Registered Public Accounting Firm
The Board of Directors and Stockholders
US Airways Group, Inc.:
We have audited US Airways Group, Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2011, based on
criteria established in Internal Control — Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO). The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the
effectiveness of internal control over financial reporting, included in the accompanying management's annual report on internal control over financial
reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require
that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all
material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists,
and testing and evaluating the design and operating effectiveness of internal control over financial reporting based on the assessed risk. Our audit also
included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our
opinion.
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. A company's
internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of
the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the
financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation
of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.
In our opinion, US Airways Group, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of
December 31, 2011, based on criteria established in Internal Control — Integrated Framework, issued by the Committee of Sponsoring Organizations of the
Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance
sheets of US Airways Group, Inc. and subsidiaries as of December 31, 2011 and 2010, and the related consolidated statements of operations, stockholders'
equity (deficit), and cash flows for each of the years in the three-year period ended December 31, 2011, and our report dated February 21, 2012 expressed an
unqualified opinion on those consolidated financial statements.
