Still thinking about it... Have wife and kids, difficult to drag them all over and I don't like 2 of the specifics of the contract, mainly that your days off include commuting (other places I've seen give you commuting days on top of the block of days off) and secondly that they don't give you business class positive space when they move you around, it's all in coach (yuck).
Zed fares on another carrier business class back and forth stateside are pricey, too.
It's a great gig if you are at a regional or about to retire state-side, but with me being on 2nd year AirTran getting ready to upgrade into a $120k a year CA seat in 2 years here, it's a harder decision, even though I'd love to be immersed in the culture. Gotta make a decision not just for me, but for the whole family.
