          Re:  Registration Statement on Form S-3
               Covering the Registration of 1,238,733
               Shares of Common Stock of Frontier Airlines, Inc.

Gentlemen and Ladies:

     We have acted as counsel for Frontier Airlines, Inc., a Colorado
corporation (the "Company"), in connection with the registration for sale of
1,238,733 shares of the Company's Common Stock (the "Shares") in accordance with
the registration provisions of the Securities Act of 1933, as amended.

     In such capacity we have examined, among other documents, the Registration
Statement on Form S-3 filed by the Company with the Securities and Exchange
Commission on or about July 3, 1996 (as may be further amended from time to
time, the "Registration Statement"), covering the registration of the Shares.

     Based upon the foregoing and upon such further examinations as we have
deemed relevant and necessary, we are of the opinion that:

     1.   The Company is a corporation duly organized and validly existing under
the laws of the State of Colorado.

     2.   The Shares have been legally and validly authorized under the
Company's Articles of Incorporation, as amended, and constitute (or will
constitute upon due exercise of certain warrants as described in the
Registration Statement) duly and validly issued and outstanding and fully paid
and nonassessable shares of the Company.

     We hereby consent to the use of our name beneath the caption "Legal
Matters" in the Prospectus forming a part of the Registration Statement and to
the filing of a copy of this opinion as Exhibit 5.1 thereto.


                                       Very truly yours,

                                       PARCEL, MAURO, HULTIN & SPAANSTRA, P.C.
