I flew for about 5 years.
I did enjoy it while I was doing it, but now, I don't bother looking back.
I remember after I had handed in my resignation I had to do a red-eye starting at about 10pm and going through about 6am. I remember thinking that if I ever thought I missed doing this job after I left, I would remember back to that time and how horrible I felt. I would have done anything to not get on that flight, the only reason I didn't call in sicj was because the flight was taking me directly home!
Also, a couple of weeks ago I got on a flight with the carrier I used to work for. Caught up with some old friends during the flight and was thinking "Man, this was a lot of fun" which it was. But then, about 10 mins before landing, mid-descent, some kid projectile vomits all-over the 2 rows infront.
I don't miss it. The social side, yes, but the reality of the job, definatley not!
Not trying to talk you out of it, it's a good job. I'm just being objective.
Have fun, if you do end-up getting in, it will be a cool experience if nothing more.
