My wife works for American Airlines, and while her department is more secure than most (and she won't be affected in the round of layoffs that AA just announced), she still lives in constant fear of being laid off when times are bad.
I work for Sabre -- the Computer Reservation System that power Travelocity, and about 3/5 of the travel agents, etc. worldwide -- and we're starting to sweat around here, too. Nothing's been announced, but we worry.
It seems like every company is -- or is thinking about -- laying people off these days. Sorry you got hit, man. :(
