If AA is your goal and you live in Dallas area, I’d say go to SWA. Training at SWA is in Dallas so you’ll be in your home city for 3 months while in training. You should be hired at AA before you even finish the type ride at SWA if you update your application . Also, you only burn the bridge with SWA and not Delta if things don’t work out with AA. Good luck. First world problems..
