Guys I can understand these sort of questions when thinking of a company move. I had the same questions running through my mind prior to joining also. The bidding sytem at LHR is complex but the basics are easily grasped. For all, concentrate on A) getting in first B)Once in concentrate on getting through TR and then released online. There is plenty of time to sort out the other stuff. BA look after you for the first 3 months or something post line training so there is no need to get hung up on trivial stuff.
