AA since I commute out of STL too. 😁
Seriously though, Delta is a great place to work. I have no idea how many AA has hired recently, but the point about the massive numbers of new hires at Delta is a good one and would certainly factor into my decision.
Personally, I’m happy I’m at Delta and not AA. Staring down 4500 newhires @ Delta vs _____ @ AA, might sway my decision as a new guy though. Depends on your age I guess. Aside from that, I’d say Delta.
