I remember pre 911 when I got my job offer from Purple, I went back to my squadron and a Delta guy told be congrats---his exact quote was:

"FedEx is a great airline and my second choice behind Delta. I'm gonna make a lot more money than you at Delta, but it's a great airline."

I guess times have changed and the double breasted boys have had to eat crow a bit, but things change overnight (STS) in this biz. One thing that will never change is that people don't have to fly if the economy goes south, but boxers seem to go regardless of what the economy is doing. I'd go with the first one who offered me a job--Purple or Brown.
