I heard from a Piedmont Dash8 pilot that they were taking over some of their routes. Apparently some Dash 8's are being returned at the end of their lease. He mentioned that Colgan has picked up a DCA-ORF run, which has been a primary route of Piedmont's (Henson's) for over 15 years.
I wouldn't be suprised if they pick up some of Midway's routes, as well. I wish they would pick another aircraft. I personally find the Saab uncomfortable, especially in the summer with no air conditioning on the ground. It's also a ramp agent's nightmare. The GPU outlet is behind the number two engine. You really stink after working a Saab flight!!
