I have to echo what others have said: it gets into your blood. After all these years, I still enjoy most of it. Sure, there's bad days but I have more good times than bad. And it's not for everyone. Flexibility and the ability to maintain a sense of humor at the worst of times is mandatory!
It's nice to not work with the same people in the same place all the time. Sometimes it's hard being away from home at special times. But that's when crew bonding really sets in. I remember one Thanksgiving when I was far away from home in some hateful hotel and the whole crew got together and made the best of it. We laughed so hard over dry turkey sandwiches and had the best time in spite of it all.
Cabin crew are a special breed, I think. Most of my "normal" friends just don't understand it. There's nothing like a good jumpseat confession to solve the world's problems.
I know I will have to leave soon and it fills me with sorrow. I don't know if I'll fit in so well in another job.
