You are joking about that. No way would anyone in their right mind choose BHX over LGW or MAN for the 380. It is scary enough putting a widebody in there now, let alone the thought of an A380!
I did say it had been identified by 'Airbus' as a
possible divert airport. That's because it is
possible to land one there. Would an airline list it? That is a different matter. Having said that, in an emergency they may be glad BHX is there...
