           FRONTIER AIRLINES REPORTS FISCAL THIRD QUARTER 2006 RESULTS

DENVER (January 26, 2006) - Frontier Airlines, Inc. (Nasdaq: FRNT) today
reported a net loss of $10.3 million, or $0.28 cents per diluted common share,
for the airline's third fiscal quarter ended December 31, 2005 compared to a net
loss of $11.1 million, or $0.31 cents per diluted common share, for the same
period last year. Included in the net loss for the three months ended December
31, 2005 were the following items before the effect of income taxes: unrealized
losses on fuel hedges of $1.5 million and gains of $0.3 million related
primarily to the sale of Boeing parts held for sale. These items, net of income
taxes, increased Frontier's net loss by $.03 cents per diluted common share.
Included in the net loss for the quarter ended December 31, 2004 were the
following items before the effect of income taxes: a gain on the sale of assets
of $0.1 million, a write down of $0.7 million of the carrying value of
expendable Boeing 737 inventory, and an unrealized loss on fuel derivative
hedges of $3.2 million. These items, net of income taxes, increased Frontier's
net loss by $.07 cents per diluted common share.

CHIEF EXECUTIVE OFFICER'S COMMENTS

Frontier President and CEO Jeff Potter said, "While this quarter's results are
in stark contrast with the previous quarter's profits, we once again saw several
promising indicators. Our mainline passenger revenue increased almost 20 percent
as we carried 14 percent more passengers on capacity growth of only nine
percent. In addition, our year-over-year mainline average fare improved for the
fourth straight quarter, increasing almost two percent on a year-over-year
basis. However, the resulting nine percent increase in mainline revenue per
available seat mile (RASM), was overshadowed by three significant aberrations to
our fiscal performance--a 35 percent year-over-year increase in fuel cost per
gallon; an estimated $4.8 million in lost revenue due to the disruption of our
Cancun and Cozumel service as a result of Hurricane Wilma; and an estimated $1.2
million in lost revenue due to the discontinuation of service to New Orleans as
a result of Hurricane Katrina."

"Outside of the significant fiscal impact of fuel and hurricanes, we did have
several operational bright spots during the quarter including a number of
record-breaking load factor days during the December holiday period. It has
taken our company and all of our employees several years of hard work and effort
to become the preferred carrier for an ever-increasing number of travelers in
Denver, and we don't intend to cede that position. We have built our product to
be the best in the industry and with our fares being on equal footing in the
Denver market, we have every confidence that customers will continue to choose
the superior product that offers them the greatest value, which is Frontier."

OPERATING HIGHLIGHTS

Mainline passenger revenue increased 19.4 percent as mainline revenue passenger
miles (RPMs) grew at a rate of 9.2 percent during the fiscal third quarter,
while mainline capacity growth as measured by mainline available seat miles
(ASMs) increased 8.6 percent from the same quarter last year. As a result, the
airline's mainline load factor was 72.1 percent for its fiscal third quarter of
2006, 0.4 load factor points more than the airline's mainline load factor of
71.7 percent during the same quarter last year. The airline's mainline breakeven
load factor, excluding special items, for the fiscal third quarter 2006
decreased 1.3 load factor points from 76.0 percent to 74.7 percent. Frontier's
mainline breakeven load factor, excluding special items, decreased from the
prior comparable period as a result of an increase in our total mainline RASM of
10.3 percent, which was significantly offset by an increase in our mainline cost
per available seat mile (CASM) to 9.32 cents during the quarter ended December
31, 2005, primarily due to increases in fuel costs, from 8.80 cents during the
quarter ended December 31, 2004, a 5.9 percent increase.



During the fiscal third quarter 2006, the airline's mainline passenger RASM
increased 9.2 percent to 8.68 cents from the same quarter last year. The
increase in mainline RASM was due to the combination of the 8.5 percent increase
in mainline yield per RPM and slightly improved year-over-year load factor.
Mainline average length of haul decreased 4.1 percent on a year-over-year basis,
primarily because the prior year included traffic from the Company's focus city,
Los Angeles, which the Company subsequently discontinued.

Mainline fuel cost per gallon, excluding unrealized hedging losses, averaged
$2.17 during the quarter ended December 31, 2005, compared to an average of
$1.55 during the quarter ended December 31, 2004, an increase of 40 percent.

Senior Vice President and Chief Financial Officer Paul Tate discussed unit costs
for the airline's quarter ended December 31, 2005, stating, "Even with our more
traditional hub and spoke model, we achieved a four percent decline in
year-over-year CASM excluding fuel, to 6.17 cents from 6.43 cents, further
strengthening our position as one of the industry's low cost producers. This
cost savings was achieved despite a nine percent year-over-year mainline
passenger unit revenue increase and a four percent length of haul decrease."

The airline's current unrestricted cash and short-term investments and working
capital as of December 31, 2005 was $222.7 million and $113.9 million,
respectively. This compares to the Company's unrestricted cash and short-term
investments and working capital for the same period last year of $149.0 million
and $55.9 million, respectively.

The airline's fleet in service on December 31, 2005 consisted of 16 owned Airbus
A319 and A318 aircraft and 33 leased Airbus A319 and A318 aircraft.

BUSINESS DEVELOPMENTS DURING THE QUARTER INCLUDED:

    o   Closed a $92 million convertible debt offering.

    o   Frontier's maintenance personnel ratified a three-year contract.

    o   Added Acapulco and Cozumel to Frontier's Mexico service, bringing the
        total number of Mexico cities served to seven.

    o   Received approval to serve Cancun with non-stop service from
        Indianapolis beginning in March 2006.

    o   Ranked number one in "On Time Arrival Performance" among all carriers at
        the 33 largest airports in America for the month of September and in the
        top five for on time arrival performance for four consecutive months.

    o   Hired Chris Collins as new Senior Vice President of Operations.

    o   Renewed contract with Intrawest Colorado to be the "Official and
        Exclusive Airline of Winter Park and Copper Mountain."

    o   Expanded service to five of Frontier's top markets, including Salt Lake
        City, Dallas, Phoenix, Las Vegas and Chicago-Midway.

    o   Received prestigious "Outstanding Corporation" award from Volunteers of
        America, recognizing Frontier's significant community contributions.

Potter concluded, "As we enter the final quarter of our fiscal year, we have
several challenges, principally in the form of record high fuel prices. However,
we have an even greater number of opportunities in front of us. Specifically, we
have announced our intention to enter the Canadian market. We will receive the
first of six new aircraft deliveries for the calendar year that will provide the
capacity for significant expansion with new frequencies and destinations. While
we recognize that the increased competition in our hometown market of Denver
will generate new pressures, we face that competition with the confidence that
comes from knowing that we have a product that is second to none, a continued
company-wide focus on cost containment that is yielding results, and an employee
group that will accept nothing less than the very best from one another and from
this company.

"In light of our positive momentum, and assuming fuel remains at an average of
$2 per gallon, we anticipate that our coming quarter will produce better
earnings results than last year's March quarter, with results expected to be
approximately break-even."



Senior leadership will host a conference call to discuss Frontier's quarterly
earnings on January 27, 2006, at 9:00 a.m. Mountain Standard Time. The call is

1.  "Break-even load factor" is the passenger load factor that will result in
    operating revenues being equal to operating expenses, net of certain
    adjustments, assuming constant yield per RPM and no change in ASMs.
    Break-even load factor as presented above may be deemed a non-GAAP financial
    measure under regulations issued by the Securities and Exchange Commission.
    We believe that presentation of break-even load factor calculated after
    certain adjustments is useful to investors because the elimination of
    special or unusual items allows a meaningful period-to-period comparison.
    Furthermore, in preparing operating plans and forecasts we rely on an
    analysis of break-even load factor exclusive of these special and unusual
    items. Our presentation of non-GAAP results should not be viewed as a
    substitute for our financial or statistical results based on GAAP, and other
    airlines may not necessarily compute break-even load factor in a manner that
    is consistent with our computation.

A reconciliation of the components of the calculation of the mainline break-even
load factor is as follows:

2.  "Yield per RPM" is determined by dividing passenger revenues (excluding
    charter revenue) by revenue passenger miles.

3.  For purposes of these yield calculations, charter revenue is excluded from
    passenger revenue. These figures may be deemed non-GAAP financial measures
    under regulations issued by the Securities and Exchange Commission. We
    believe that presentation of yield excluding charter revenue is useful to
    investors because charter flights are not included in RPMs or ASMs.
    Furthermore, in preparing operating plans and forecasts, we rely on an
    analysis of yield exclusive of charter revenue. Our presentation of non-GAAP
    financial measures should not be viewed as a substitute for our financial or
    statistical results based on GAAP. The calculation of passenger revenue
    excluding charter revenue is as follows:

4.  This may be deemed a non-GAAP financial measure under regulations issued by
    the Securities and Exchange Commission. We believe the presentation of
    financial information excluding fuel expense is useful to investors because
    we believe that fuel expense tends to fluctuate more than other operating
    expenses, it facilitates comparison of results of operations between current
    and past periods and enables investors to better forecast future trends in
    our operations. Furthermore, in preparing operating plans and forecasts, we
    rely, in part, on trends in our historical results of operations excluding
    fuel expense. However, our presentation of non-GAAP financial measures
    should not be viewed as a substitute for our financial results determined in
    accordance with GAAP.
