Why park the 140s? I can see why the 135s can be parked. If you have a 145 go out with 6 empty seats, then you have a full 140. I know its smaller, but is that much of a difference when flights go out with open seats on them. You have to remember that all flights arent full all the time. Even the CRJ which goes out empty all the time.

Look at the loads so far for the aspen flying thats about to start.
