agree… life at one of the major airlines is awesome in comparison most non-flying jobs and working at a smaller national, corporate gig, and/or regional carrier (from what i've heard) that works you to death with crappy pay, benefits package and retirement program.

Normally the ones that are chronically unhappy are either (1) unhappy with life in general, (2) don't drink enough, or (3) commute to work. If you can do less of number 1 and 3 and try to do more of 2 you'll be fine.
