According to flight attendant, the nicer you are to them, the more they will do for you. Ran out of beef? Ask politely and they will get you a fillet mignon from first class. Your neighbour is noisy? Tell them nicely and we might be able to get you a better seat. Be nice to the ticket agent and they will pretty much always let you get away with overweight bags. If you were funny, I'd even not charge you for bags.
