JOaT,
Yes, I work for an airline, my last jumpseat ride was a familiarisation flight. Although I just don't feel the bug bite when I'm up there, I would love to try for a PPL, a friend has a fATPL and instructs to earn a few quid on the side so that's not a problem! I bet you are right, I'd probably get hooked and spend all my hard-earned(?) on it, but then why not....That's what it's there for!
