With your situation it probably doesn't matter either way... you will get some 121 time.. get current, and see what flying Pax is all about. However, I would probably choose any of the big players if I could live in base. NOT commuting will make a year or two stay at the regional level semi bearable. Hopefully then in a couple years as the age 65 retirements materialize... with some recent 121 time and your military background you very well might get picked up early in that hiring cycle. Right now that is probably the best you can expect. Good luck......
