Top marks for BA!
Few weeks back I was positioning on a BA short haul flight (not in uniform). I was one of the last to board and noticed that every seat surrounding my aisle seat was occupied but there were some empty ones towards the rear. I turned to ask the attendant behind me who happened to be the Purser if it was OK to go straight to one of the empty seats at the rear when he asked "would I mind" taking one of the seats by the over-wing emergency exit instead which was empty. He then proceeded to ask a chap from the row behind on the other side if he would do likewise.
The point about this is that those seats were just in front of the curtain separating economy from exec (it was quite far back on this day). We were Then treated to the full exec service. Not only that but on asking us to take those seats, and subsequently, the purser behaved as though we were doing him a favour (putting proper safety measures in place) and not the other way round.
Pure CLASS!
