Comair WILL NEVER be flying for anyone else. They will remain Delta's biatch until DL no longer needs them. UAL doesn't want any piece of crap 50 seater's. The closest Comair will ever get to United Express is the ground handling, but that's it.

My guess is, IF this flying is really up for grabs, it will probably go to SkyWest. They already fly for UAL, the Mesa Dash 8s in DEN could be easily replaced by the Brasilia's.

-BOHICA!
