I'm a little confused.....
Which gates are bmi using now for internationals? Are the old BA 5A-D gates now in use as bmi internationals? If not, it's going to be a hike back to the other side of the terminal.
What about the other old "domestic" gates that are off the green mile, that used to be primarily BA domestics. Are these now international and sealed off from the green mile?
Not been in LHR for a while, as you might notice!
