Seatbacks upright and armrests down
'Massive' FAIL. Airline seats aren't deisgned to join together to make one seat... unless these larger people don't mind an armrest up their jacksy upon take-off and landing or sticking into their blubbery backs during the flight it doesn't really make a whole lot of difference I would have thought! Just as well they all have a jolly sense of humour... according to the stereotype.
