Pre 9/11 I carried Paul McCartney on a 747-400. I told the captain he was on board and he asked me to invite him to the FD.
I took him up the stairs and on reaching the top he exclaimed “wow this is really nice it’s like a private jet”. I realised that, of course, he had only ever flown in First Class in the nose and had never seen the lovely Club Upper Deck!
I had to persuade him he was better off spending his dosh on First Class travel.
