                    CERTIFICATION OF CHIEF EXECUTIVE OFFICER
                         PURSUANT TO SECTION 302 OF THE
                           SARBANES-OXLEY ACT OF 2002

I, Philip H. Trenary, certify that:

         1.       I have reviewed this Quarterly Report on Form 10-Q of Pinnacle
                  Airlines Corp.;

         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 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 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
                                    the end of the period covered by this report
                                    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
                                    registrant's most recent 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 officer and I have
                  disclosed, based on our most recent evaluation, to the
                  registrant's auditors and the audit committee of registrant's
                  board of directors (or persons performing the equivalent
                  function):

                           a)       All significant deficiencies in the design
                                    or operation of internal controls which
                                    could adversely affect the registrant's
                                    ability to record, process, summarize and
                                    report financial data and have identified
                                    for the registrant's auditors any material
                                    weaknesses in internal controls; 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.
