I was in a similar situation 1.5 years ago (AA gave me a class date while I was in Delta indoc). QoL was by far my #1 concern. I left Delta for AA because I wanted to live in Tucson and be based in PHX, and because the greater retirements looming at AA. Both factors weighed heavily in my decision, so I left Delta. Not having to wear a hat is a bonus!

One thing I learned is that when you consider communting, try to get very specific intel. For example, I thought that communting PHX to LAX would be easier than TUS-LAX. However, there are so many people trying to do it, that it offsets the greater number of flights and broader time ranges. Everyone I have talked to doing that commute hate it, but TUS-LAX was easy.

It wasn't all rosy, though. I had to spend the night in LAX once or twice a month (including the crew room twice when there were no close hotels available), and the last flight left around 7pm. In contrast, the last LAX-PHX flight was after 10pm.

I also recommend getting specific data on the seniority in the bases you want to end up at. They vary a lot, and that will make a big QoL difference. Investigate things like how easy is it to pick up, trade and/or drop trips, how much premium available in a base, how many redeyes, how many commutable trips, etc.

All that said, we don't know what bases will close, how contracts will evolve, etc. Both jobs will be great, and I won't second guess my decision. (Although it does sting a little when profit sharing time hits).

FWIW, while there are plenty of things that need attention in our contract, the pilots I fly with don't let it impact our trips. Same thing goes for the different tribes at AA. The crews have been great!
