If I was new to the industry I would choose the following airlines.

Compass
Endeavor
Skywest
Commutair(has to be better then any of the following)
Piedmont
PSA
Mesa
Envoy(I've said it before, Envoy is the new Mesa)
Hell wait a year, and republic will be Jr. And hiring like crazy

I would choose XJT/ASA but don't even have a Luke warm feeling about them.

Does anyone really choose TSA and Go jets anymore, or have they given up trying
