      (a)   The reasons described in reasonable detail in Part III of this form
            could not be eliminated without unreasonable effort or expense;

[X]   (b)   The subject annual report, semi-annual report, transition report on
            Form 10-K, Form 20-F, 11-K or Form N-SAR, or portion thereof, will

PART III -- NARRATIVE

State below in reasonable detail the reasons why the Form 10-K and Form 10-KSB,
11-K, 20-F, 10-Q and Form 10-QSB, N-SAR, or the transition report or portion
thereof, could not be filed within the prescribed time period.

      The one-day delay in filing of Mesa Air Group, Inc.'s Form 11-K for the
      fiscal year ended September 30, 2003, is primarily attributable to its
      inability to timely gather the required information. The Form 11-K was
      filed on March 30, 2004.

                                                                  [X] Yes [ ] No

      from the corresponding period for the last fiscal year will be reflected
      by the earnings statements to be included in the subject report or portion
      thereof?

                                                                  [ ] Yes [X] No
