So what things could go wrong?
Check in system failure? No problem as I will OLCI and PYOBP.
Security machine failures? As likely to happen as any other terminal/airport as these are in use elsewhere so machines should have been debugged by now?
Baggage system failure? I will have hand luggage only and this would be BA/BAAs worst nightmare if this broke down in the first month of use!
Airstairs failure? Wouldn't happen to them all at the same time??! I hope not!
Lounges run out of Champagne and Bacon Butties? CANCEL MY FLIGHT! I want a full refund and 100k BA Miles!
