PINNACLE AIRLINES REPORTS THIRD QUARTER EARNINGS OF $12.6 MILLION

MEMPHIS, TENN. October 28, 2004--Pinnacle Airlines Corp. (NASDAQ: PNCL) today
reported third quarter operating revenue of $168.1 million, resulting in revenue
growth over the comparable period in 2003 of 40%. The company produced operating
income of $18.5 million, an operating margin of 11.0%, and net income of $12.6
million, or diluted earnings per share ("EPS") of $0.58.

Operating revenue for the nine months ended September 30, 2004 was $454.1
million, resulting in revenue growth over the comparable period in 2003 of 38%.
The company produced operating income of $49.8 million, an operating margin of
11.0%, and net income of $30.4 million, or diluted EPS of $1.39.

Interest expense for the third quarter of 2004 decreased by $0.8 million
compared to the same period in 2003 due primarily to decreased borrowings from
Northwest.

Income tax expense for the three months ended September 30, 2004 decreased by
$1.4 million over the same period in 2003, due primarily to a $1.7 million
reduction in amounts previously estimated for 2004 and 2003 income taxes.

The Company's available seat miles ("ASMs") increased by 58%, block hours
increased by 56%, and cycles increased by 42% during the three months ended
September 30, 2004, compared to the same period in 2003. The Company's ASMs
increased by 58%, block hours increased by 53%, and cycles increased by 38%
during the nine months ended September 30, 2004, compared to the same period in
2003. The term "block hours" refers to the elapsed time between an aircraft
leaving a gate and arriving at a gate, and the term "cycles" refers to an
aircraft's departure and corresponding arrival. The increases were driven
primarily by the growth in the Company's fleet of Canadair Regional Jets
("CRJs"), 8 of which were added during the three months ended September 30,
2004. By adding 39 aircraft since September 30, 2003, the Company has grown its
fleet by 56% to include 109 CRJs at September 30, 2004.

In connection with its Initial Public Offering of stock in November 2003,
Pinnacle and Northwest Airlines amended their operating agreement to grow the
Company's fleet to 129 CRJs by the end of 2005, extend their agreement through
2017 and lower the target operating margin provided in the agreement from 14% to
10%. Under the 14% target margin in effect during the three months ended
September 30, 2003, the Company recorded passenger revenue of $118.5 million and
operating income of $16.6 million, an operating margin of 13.8%, and net income
of $8.7 million, or diluted EPS of $0.40. If the reduced target margin had been
in effect during 2003, Pinnacle's growth during the third quarter of 2004 in
passenger revenue and operating income would have been approximately 48% and
64%, respectively, compared to the same period in 2003.

The company generated $25.6 million of cash from operations during the nine
months ended September 30, 2004 and had $38.1 million in cash and cash
equivalents on September 30, 2004.

"Pinnacle experienced yet another quarter of exceptional growth," said Philip H.
Trenary, President and Chief Executive Officer. "Despite the ongoing challenges
we face in the regional airline industry, our People continue to perform at
superior levels, as evidenced by our above-plan financial results for the
quarter. Our focus on productivity remains the primary driver behind lower than
expected costs."



Pinnacle's third quarter results will be discussed in more detail on October 28,
2004, at 2:00 p.m. CST via teleconference. The live audio Webcast of the call
will be available on Pinnacle's Web site at www.nwairlink.com. There will also
be a replay of the call available beginning at approximately 5:30 p.m. CST at
the same Web address.

The Company's Form 10-Q for the quarter ended September 30, 2004, including
exhibits, will be available on the Company's website at www.nwairlink.com
beginning October 28, 2004.
