I heard the opposite to that BBB.
I thought it was decided that it would cost too much to give us all hats and that in 2012/2013 they are bringing in a new uniform for all! I doubt BA will give any of us a vote whether we want one or not. I think they will be the ones making that decision! We shall just have to wait and see.
However I personally don't mind at all wearing one, or for that matter not wearing one but I would like all female cabin crew to wear the same uniform. It is a very strange situation to choose to have some crew wearing hats and some not!!I don't think it is a good idea by BA at all!
I don't mind what they decide to do but I really feel we should all look the same and I do agree that the hat looks lovely.
