Apologies if this has been covered before, but I couldn't find a thread which touched on this directly.
I had a few flights last year where I was sitting happily in T5B Galleries when "Gate open" (or words to that effect) showed up on the board. I duly moved out, only to arrive at the desk to find boarding not yet started. Now I have an upcoming flight where I suspect I shall be connecting from B to a C gate. I'd hate to rush from the lounge to find myself hanging around in a crowd at the gate. I've no wish to be that guy running up just before they close the gate, but don't really need to be one of the first on either
When do you leave the B lounge?
