                      PINNACLE AIRLINES REACHES NEW HEIGHTS

                                  MARCH TRAFFIC

MEMPHIS, TN--(MARKET WIRE)--Apr 4, 2006 -- Pinnacle Airlines, Inc., a wholly
owned subsidiary of Pinnacle Airlines Corp. (Nasdaq:PNCL), has always been
recognized as one of the nation's most reliable airlines. Now, the carrier has
set a new standard, breaking its internal record for the most consecutive days
without a flight cancellation. Between March 24 and March 30, Pinnacle operated
100% of its scheduled flights. In fact, the airline operated a string of 6,020
consecutive flights before a weather system in the Mid-West forced a
cancellation. During this period, 94.6% of all Pinnacle flights departed on
time, using Department of Transportation guidelines. Importantly, Pinnacle
transported approximately 216,700 Customers over this specific time frame. And,
Pinnacle has completed at least 99.0% of its scheduled flights for four of the
past five months.

Pinnacle Airlines operates 697 daily flights to 110 destinations in the United
States and Canada, ranging from Halifax, Nova Scotia to Salt Lake City, Utah,
and from Quebec City, Quebec to Gulfport, Mississippi. Nearly one-third of
Pinnacle's flights operate in the Northeast corridor of the U.S. and Canada, an
area prone to significant weather and Air Traffic Control delays.

"I'm not aware of any carrier of our size and scope with such a streak," said
Philip H. Trenary, Pinnacle President & CEO. "Although this is an incredible
achievement, no one should be surprised. Our People have always done more with
less than any of their peers at any airline, anywhere, including the majors.
This is the result of their great professionalism, dedication and teamwork
second to none. As we navigate these very challenging times our People are again
proving that they are 'Simply the Best.'"

Separately, Pinnacle released its passenger and traffic levels for March 2006.
For March, Pinnacle flew 465.3 million Available Seat Miles ("ASMs"). Revenue
Passenger Miles ("RPMs") expanded 8.5% to 356.5 million. Passenger Load Factor
was 76.6%, an increase of 6.5 points over March 2005 levels. Pinnacle
transported 745,635 Customers during the month, 13.4% more than the same period
last year.

Also for the month, Pinnacle operated 35,455 block hours and completed 21,461
cycles. The term "block hour" refers to the elapsed time between an aircraft
leaving a gate and arriving at a gate, and the term "cycle" refers to an
aircraft's departure and corresponding arrival.
