Regional carrier Colgan Air flies under the flags of United and US Airways. As US Airways Express, Colgan Air serves cities in the eastern US and operates as United Express out of Washington, DC. Overall, Colgan Air schedules over 200 departures per day, serving approximately 40 cities in 10 states, as well as Canada. The carrier's fleet of around 60 turboprop aircraft includes Saab 340s and Bombardier Q400s. Parent company Pinnacle Airlines Corp. filed for Chapter 11 bankruptcy protection in April 2012 and plans to wind down Colgan's operations by the end of 2012. Pinnacle Airlines initially bought Colgan Air from the founding Colgan family for $20 million in 2007.
