There are just too many aspects of the story that don't add up. I didn't realise he claimed to have sat in the toilet during take-off. This is impossible. The door is opened, the toilet checked and the door locked before the take off roll begins. Boarding passes are checked before passengers enter the security screening area. How did he get round that? I fly often from MAN Terminal 3 and I assume the same system operates in Terminal 1. As I said in a previous post, Jet2 pre-assigns seating, unlike easyJet and Ryanair. He just couldn't get on and sit in a free seat, confident it hadn't been pre-assigned to someone else.
I don't buy this story.
