Hi Joybells,
51 the higher age bracket?? Let me tell you a little story that may inspire you!!!
I fly for BA and have just done a trip to Japan. One evening on my stopover I along with one of the other crew went to a noodle resturant a bit basic but very nice food!! We were joined at our table by three flight attendants from United. I'd say they were all in there 50's.
We had a great conversation mostly about the airline industry and of course about conditions within our own airlines.
Anyway during the course of the conversation they started to tell me that on there particular crew there was a flight attendant called Iris and she was the most senior. In fact I think they said her seniority number was something like 00001!!!
Iris is still flying at the grand old age of 83!!!! Now I know there are people within the flying community that would say she should have given up years ago, but I really take my hat of to this women.
So Joybells my advice to you - GO FOR IT!!!! XX
