I think it fair to say that most people envisioned themselves flying for a major airline when they first started out in their careers.
Personally, I'm quite content where I am right now. The salary is pretty good, health insurance is excellent and I live in base, so no commuting. That alone is worth a lot to me.

Who knows what the future will bring, especially in this business, but I currently don't have my resume out.
I'm not about to start commuting to JFK to sit reserve just so I can fly an A320. I don't care how much they pay me.
