Well, my 1st attempt at change ended in;

You are already checked in for the flight found. Please proceed to the airport.

Can one stay in the Concorde Lounge for 20 hours then?

Edited to add - oh dear, & my 2nd attempt through MMB has come up with - Seat request not available within 24 hours of departure.
Seat(s) will be allocated at time of check-in.



Can anyone tell me how empty F is on the 20:10 to YYZ tomorrow? Mind you - won't take much for my 2e &f to be pinched at the last minute anyways.Lil staff or BA Gold u/g or two even.
