EXHIBIT 99.1 PRESS RELEASE 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.'"
