Report of Independent Registered Public Accounting Firm
The Board of Directors and Stockholders
AMR Corporation
We have audited the accompanying consolidated balance sheets of AMR Corporation as of December 31, 2006
and 2005 and the related consolidated statements of operations, stockholders’ equity (deficit) and cash flows for
each of the three years in the period ended December 31, 2006. Our audits also included the financial statement
schedule listed in the Index at Item 15(a)(2). These consolidated financial statements and schedule are the
responsibility of the Company’s management. Our responsibility is to express an opinion on these financial
statements and schedule based on our audits.
We conducted our audits 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 the financial statements are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by management, as well as evaluating
the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated
financial position of AMR Corporation at December 31, 2006 and 2005 and the consolidated results of their
operations and their cash flows for each of the three years in the period ended December 31, 2006 in conformity
with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule,
when considered in relation to the basic financial statements taken as a whole, present fairly in all material
respects the information set forth therein.
As discussed in Notes 1, 9, and 10 to the consolidated financial statements, in 2006 the Company changed its
method of accounting for share-based compensation as required by Statement of Financial Accounting Standards
No. 123(R), “Share-Based Payment,” changed its method of accounting for retirement benefits as required by
Statement of Financial Accounting Standard No. 158, “Employer’s Accounting for Defined Benefit Pension and
Other Postretirement Plans” and changed its method of accounting for planned major maintenance activities at
one of its operating subsidiaries as required by Financial Accounting Standards Board Staff Position No. AUG
AIR-1, “Accounting for Planned Major Maintenance Activities.”
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the effectiveness of AMR Corporation’s internal control over financial reporting as of December
31, 2006, based on criteria established in Internal Control—Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission and our report dated February 21, 2007 expressed an
unqualified opinion thereon.
