Charles J. Colgan founded fixed-base operator Colgan Airways Corporation at Manassas Airport in 1965. It began scheduled service under contract with IBM in 1970 between Manassas, Virginia, near Washington, D.C., and Dutchess County Airport near Poughkeepsie, New York. In 1986 Colgan Air received its first airline contract with New York Air operating as New York Air Connection with Beechcraft Model 99's, Beech 1900C's, and Shorts 330's. New York Air was merged into Continental Airlines on February 1, 1987 at which time Colgan became a Continental Express feeder carrier. Jetstream 31 aircraft were then acquired. Colgan later sold to Presidential Airways which was also a Continental Express operator. In mid 1988 Colgan and Presidential switched from a Continental Express feeder to become a United Express feeder carrier. This operation under the United Airlines banner also only lasted about one year before Presidential shut down in 1989.
