Have a read through some of the postings dealing with security at UK airports...........better wear a helmet!
Most crew actually fall over because of antics back in the hotel (wrecking a room , not paying the room bill, being rude to hotel staff etc ) as the hotel staff then report the crew to the airport security peeps for being under the influence......
(Yes....as they heard them run through the corridors 2 hours before check out.....).
