Exhibit 31.2


I, Thomas W. Horton, 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.
