unhappyyorkshirelass - I worked as cabin crew for BA for 6 years, left in '99 and to be honest you truly know when enough is enough! I thoroughly enjoyed the first few years, especially going to new places and having a laugh ............ but it does start to wear a bit thin after a while, you do become drained and saying 'chicken or beef', 'tea or coffee' to hundreds of people on a 747 made me brain dead!
BUT I wouldn't have swapped my 6 years for anything and I have no regrets, especially as I met some truly fantastic people flying! I've since moved on to another area of aviation that better suits me - and my brain!
So, my advice is to enjoy it while you can and then go with your instincts!
