United is increasing there Express flying (see link). Maybe if TSA gets rid of AA Flying or gets out of that 50 seat bull****, United will give them more flying on bigger planes.
Honestly, I can bet that the flying would just go to GoJet. Why? I don't know the exact details, but for TSA to set up shop for the CRJ, I can only imagine it'd involve a lot of work on their part (e.g., new ground school instructors, updating manuals, FAA involvement in all that, etc).
Why go through all that trouble when literally five doors down in the same building is an operation that's already up and running?
Anyway, so much for being near the top of the callback list.

Actually, so much for being called back at all.
