I live in Denver....turned down UAL. You go with what you know at the time you know it....UAL was a different airline in 2015. I'm 43 and UAL's hired something like 6k people since 2021. As a WN CA, I'd be a complete dumbass to leave.

If you're 25 with little to no seniority, might make sense to bail for UAL. You can't toss out generalized statements like that without knowing the OP's wants/needs/age/etc....If they don't want to sit in a sim weekly, TK is out. If they want QOL over pay, then new hire upgrade to the 737 is out. If they want to maximize their pay at work to get the most days off at home, maybe UAL is out. If they don't want anything to do with flying planes every week but want to get paid, maybe SWA is out in favor of LCR at UAL.
