Virgin Atlantic
Hi there,
I used to work for them and hated it from the initial training course. I found the airline to be MOSTLY (not all) unfriendly, very junior/senior, !!!! wages and basically crap. However I met a few good friends while I was there. but I would inform you sister that are much better and more friendly airlines to work for.
Sorry to put a downer on the situation but just giving you some advice.
Good luck!
