Don't mention it...
For those who are airline employees do you prefer not to mention it should the question of your line of work come up in conversation with a seatmate ?
If asked, I will quietly mention it but sometimes it opens up a can of worms. I love it though when someone is doing a lot of complaining about the airline or flight and goes on and on and then starts getting around to my employment in which case I "admit" to working for this airline.
They are sometimes embarrassed but I always reassure them they have every right to complain. Some of my coworkers think it is not right to mention it but why should I lie? On the other hand I have lied and mentioned a line of work I was in before I worked for the airlines - saved myself alot of whining in my ear.
