So BA sent the flight to MME even though NCL opened whilst the flight was in the air?
LTN Phobia - not sure there's much value in jumping to BA's defence as a default position, but the late NCL flight wasn't full.
It's at least a relief we all know how good BA is at organising short notice coach transfers; the poor guys often seem surprised that a scheduled flight has landed at T5 based on my experiences of hanging around on board waiting for coaches to arrive.
Did BA pay the departure fees for people leaving MME?
