ExpressJet/ASA would be ideal with a large ATL base that will not close down, on a whim. Commuting sucks and it isn't worth the effort in your situation. Good contract, but the upgrade time is a while. With your heavy military TPIC time, I wouldn't worry about upgrade. Delta really likes ASA guys/gals and I would guess you wouldn't even be there more than a year. Delta should give you a call if everything else checks out (GPA, volunteer, masters?).
