                 Frontier Airlines to Begin Focus City Expansion from
                            Los Angeles International Airport
    Frontier to Begin New Non-Stop Service from Los Angeles to St. Louis,
Minneapolis and Kansas City as well as Denver to Anchorage and Washington-Dulles

         DENVER (Dec. 18, 2003) - Marking the first expansion of point-to-point
routes outside of its Denver International Airport (DEN) hub, Frontier Airlines
(Nasdaq: FRNT) today announced plans to begin service between Los Angeles International
Airport (LAX) and Kansas City International Airport (MCI), Lambert-St. Louis
International Airport (STL), and Minneapolis/St. Paul International Airport (MSP),
beginning Apr. 11, 2004.  The airline will operate two daily non-stop flights
between Los Angeles (LAX) and each of these three cities.  The new routes will
complement Frontier's existing six daily non-stops between Denver and Los Angeles,
as well as its service between Denver and Ontario (ONT), San Diego (SAN) and Orange
County (SNA).
         In addition to Frontier's expansion in Los Angeles, the airline also
announced separately today that it will start one daily non-stop flight from its
Denver hub to Anchorage International Airport (ANC) on May 9, 2004 and two daily
non-stops to Washington Dulles International Airport (IAD) on Apr. 11, 2004, as
well as two-daily non-stops to El Paso International Airport (ELP) on Feb. 8, 2004
that will replace its existing service via Albuquerque.
         "Today marks a critical and exciting juncture for Frontier Airlines, its
employees and its loyal customers," said Senior Vice President of Marketing Sean
Menke. "We have focused on the growth of our hub in Denver for the past ten years,
and we feel comfortable that we are now at a point that we can begin to fully
leverage and utilize that asset as we begin to offer non-stop service outside of
Denver to complement our hub schedule.  The result will be better utilization of
our planes as well as our facilities, and more options for travelers in Los Angeles,
which has always been our most popular destination.  We look forward to making our
mark in Los Angeles, one of the world's greatest destinations, and complementing
the extensive service we already offer in Southern California."
