EXHIBIT 31.2

                                 CERTIFICATIONS

         I, Bradley D. Tilden, certify that:

         1.       I have reviewed this annual report on Form 10-K/A of Alaska
                  Air Group, Inc. for the year ended December 31, 2003;

         2.       Based on my knowledge, this annual 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 annual 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 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)) for the registrant and we 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) 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 December 31, 2003, based on such
                  evaluation; and

                  c) disclosed in this report any change in the registrant's
                  internal control over financial reporting that occurred during
                  the 2003 fourth fiscal quarter 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 officers 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.
