Former corporate guy here too, now at SkyWest (going on almost three years). I've enjoyed it a lot more than I thought I would, and am now quite convinced that 121 is for me. This despite having ZERO interest in the airlines a few years ago. Funny how things change!
I agree with Droops that morale seems to be an issue at ExpressJet (and a few others). Where are you hoping to be based? Are you open to other possibilities? If I were starting over again at the regionals, I'd probably be looking hard at Compass...
