GREAT LAKES AVIATION TO DISCONTINUE UNITED EXPRESS FLIGHTS AT FAIRMONT, MINNESOTA

Spencer, Iowa – November 22, 1999 – Great Lakes Aviation, Ltd. (NASDAQ:GLUX) announced today the termination of its United Express flights at Fairmont, Minnesota effective January 5, 2000. The last date for United Express flights between Fairmont and the Twin Cities will be January 4, 2000.

This action is in response to an order issued by the U.S. Department of Transportation on November 19, 1999. By this order, the Department of Transportation is terminating the subsidy eligibility of Fairmont, Minnesota because the subsidy per passenger far exceeds the $200 per passenger statutory ceiling.

In the order, the Department of Transportation noted that three different commuter carriers have served Fairmont beginning in 1981, and none have been able to make the service viable. The Department further noted that history strongly suggests that Fairmont's traffic-generating potential is very limited, and the prospects for its traffic to increase enough to bring the subsidy per passenger under $200 appears remote.

Great Lakes Aviation and United Airlines will coordinate the rebooking of passengers who are ticketed for travel January 5, 2000 and later. Refunds without penalty will also be available should alternate arrangements not be satisfactory.

Great Lakes Aviation is currently providing United Express service at 67 airports in fourteen states with a fleet of eight Embraer EMB-120 Brasilias and 40 Beechcraft 1900D regional airliners.
