No matter what they have said, it is too soon to get a reply, especially for cabin crew. I waited 3 months for my reply and another three months to get a course. Bear in mind that there is lots of restructuring going on in ba at the moment and especially regarding cabin crew there may be longer delays, as they may consider what to offer (temp or new fleet).
Just some advice...I know it is very tempting but try to avoid calling them asking for news. They are well organised and they will call you when they have processed your application. And remember...no news is good news
I wish you best of luck...
