Sick Squid is right, your job is as much fun as YOU make it. I am always suprised by which pilots turn out to be the most fun inflight and on layovers! The same with crews, you expect the young ones to be the most fun but sometimes it is the 50 year olds that have you in stitches inflight. Go for the airline that is the most financially stable, some trips will be a joy and some won't. That is true for all airlines. Good luck!
