Money. Purple and Brown will pay you much more over the long term, especially in retretirement. If those fall through this is about on par or maybe a little worse than landing at a ULCC, depending on how you value certain benefits. There's lots of discussion to be had here, depending on how you invest v. direct contributions elsewhere, etc.

As for whether this is a destination for the right person, that all depends on the person. You'll never impress anyone with Atlas Air stickers on your bag. That's not to imply that pursuing a feeling of "making it" is dumb, but that's an itch you'll have to scratch some other way. The newness of our flying wears off over time. The joy of flying to Peoria is about the same as the joy of flying to Ramstein. I still like flying, but the destinations become less important over time. That said, no crash pad, no commuting space-a and the ability to set your own level of involvement is pretty good.

Hope this helps. If not, sorry to make you read this much.
