If you live in ATL I would definitely try for ASA. The CLT commute looks like it has 8 mainline DL flights on plus Aitran and US, so it shouldn't be too bad. Commuting to PDTs bases shouldn't be too bad from ATL, but I personally wouldn't want to commute if you don't have to. ASA is is hiring, so the way I see it you don't have to.

I haven't worked at ASA or PSA, so I can't comment on those. Hopefully someone who has actually been working for one of those airlines for more than year will post and give you more info about QOL.
