From your kind direction I got all the information I need thanks Skipness, Farci, Hartington, ExXB and jubilee. Pprune at its best.
Beside Wetherspoon Express T1 near gates 77-90 there is a desk with departure information displayed. Is this a security desk or an airport information desk? We were told by a gentleman sitting at it 'not to worry the flight was being held for us. They know you are on the way'. Just puzzled how he came into the equation and knew about us!
