No, all you have to do is bid for the commands, it doesn't matter if there are none available. But it is a little premature to be worrying about this at this stage. No-one knows what BA will look like in 18 years, it may have expanded significantly or it may no longer be with us. The changes that have happened in the last 12 years since 9/11 have been huge, why does everyone expect that nothing will change in the next 18?
