Choices:
1/2 (tie) United and American.
3. Delta
I'd be incredibly happy if any of them picked me up, but for me it's about one thing and one thing only: Driving to work.
I would live in Houston or Dallas forever. I could live in Atlanta or close to it. Those are my choices, in that order, and that is what it is based on. I'm 35, so I'll never be super-senior anywhere, but I don't give a crap about that. I'll sit reserve for a long time if I can sit at home and drive to work. Reserve ain't so bad if you can do that, especially senior reserve.
Planes: don't give a rat's ass
Flying: don't much care, at least to a point.
Pay and benefits: they're all pretty close anyway, some are better than others, but all pay you PLENTY to live on.
It's like real estate for me.....location location location. If I had my pick, I'd pick one of the three based SOLEY on where I want to spend the next 30 years living.
Of course, even though DL is third on the list, if they called me tomorrow I'd pack my happy-go-lucky a$$ up with a big $hit eating grin on my face and never look back, all while counting my lucky stars.
We'll see.
