Having completed the Virgin entry exams and inteview last year, only to be told they are not taking anybody on that year I feel I can give you a bit of advice here.
They may invite you to sit the entry tests and so on based on your predicted grades and offer you a position subject to you acheiving those grades required. They also mentioned having a few 'reserve' people should anybody turn down their offer or doesn't achieve their predicted grades. Best idea is to give them a bell and see what they have to say.
I also hear that Thomas Cook will be looking for apprentices to start in September so may be worth keeping an eye out for them too.
