If i was you, don't believe anything until you see it, as things change within 5 minutes. Even once you start flying, you learn not to believe anything until you see it, its one big rumour mill. Don't think you'll be going to London either.
As said before, i know quite a few people who have gotten to the medical and security stage and have still got the thanks but no thanks letter and they had nothing wrong with them or criminal history so................I know it's hard not to get excited, but just also prepare for the negative response incase of disappointment. QF won't think about things like you having to spend $300 on medical/secuirty expenses etc as if you won't do it, then the next person in line will.
All i can say is believe it when you see it. Even after i got the call, i said i wouldn't believe i had the job until i had signed the contract and was in the uniform.
Good luck with everything.
