Exhibit 31.2


I, James A. Beer, certify that:

1. I  have reviewed this quarterly report on Form 10-Q of
   American Airlines, Inc.;

2. Based on my knowledge, this report does not contain any
   untrue  statement of a material fact or omit  to  state  a
   material  fact necessary to make the statements  made,  in
   light of the circumstances under which such statements were
   made, not misleading with respect to the period covered by
   this report;

3. Based  on my knowledge, the financial statements,  and
   other financial information included in this report, fairly
   present  in all material respects the financial condition,
   results of operations and cash flows of the registrant  as
   of, and for, the periods presented in this report;

4. The registrant's other certifying officer(s) and I are
   responsible  for  establishing and maintaining  disclosure
   controls and procedures (as defined in Exchange Act  Rules
   13a-15(e) and 15d-15(e)) and internal control over financial
   reporting (as defined in Exchange Act Rules 13a-15(f)  and
   15d-15(f)) for the registrant and have:

   (a) Designed such disclosure controls and procedures, or
       caused such disclosure controls and procedures to be
       designed under our supervision, to ensure that material
       information relating to the registrant, including its
       consolidated subsidiaries, is made known to us by others
       within those entities, particularly during the period in
       which this report is being prepared;

   (b) Designed such internal control over financial
       reporting, or caused such internal control over financial
       reporting to be designed under our supervision, to provide
       reasonable assurance regarding the reliability of financial
       reporting and the preparation of financial statements for
       external purposes in accordance with generally accepted
       accounting principles;

   (c) Evaluated the effectiveness of the registrant's
       disclosure controls and procedures and presented in this
       report our conclusions about the effectiveness of the
       disclosure controls and procedures, as of the end of the
       period covered by this report based on such evaluation; and

   (d) Disclosed in this report any change in the registrant's
       internal control over financial reporting that occurred
       during the registrant's most recent fiscal quarter (the
       registrant's fourth fiscal quarter in the case of an annual
       report) that has materially affected, or is reasonably
       likely to materially affect, the registrant's internal
       control over financial reporting; and

5. The registrant's other certifying officer(s) and I have
   disclosed, based on our most recent evaluation of internal
   control  over  financial reporting,  to  the  registrant's
   auditors and the audit committee of the registrant's board
   of   directors  (or  persons  performing  the   equivalent
   functions):

   (a) All significant deficiencies and material weaknesses in
       the design or operation of internal control over financial
       reporting which are reasonably likely to adversely affect
       the registrant's ability to record, process, summarize and
       report financial information; and

   (b) Any fraud, whether or not material, that involves
       management or other employees who have a significant role in
       the registrant's internal control over financial reporting.
