He mentioned we keep lists about you and share it with crew. We have better things to do than keep track of passengers we may not particularly like.
40 countries? I'll give $100 to the first person to list the 40 countries QF has flown to over the last 12 years.
First class only? We don't have dedicated first positions. You work either F/J or W/Y.
He looked after Katy Perry? She was onboard, but he didn't serve her. He was working in economy, while she was travelling in either F/J.
I'm sure there are more but I won't be picking up the book to find out what else is most likely highly exaggerated or just down right incorrect.
As I said, you've got a pilot and a crew member with their own threads more or less who have always been happy to provide factual, honest responses to your questions about their respective jobs.
