According to Arthur Berkowitz, 57, the obese man spilled over into his personal space and he could not move because the plane was full so he was forced to stand up.
Later, Berkowitz said the co-passenger asked sorry for what had happened. "The first thing he said to me was: 'I want to apologise – I"m your worst nightmare"," the Daily Mail quoted Berkowitz as saying.
The route from Anchorage to Philadelphia is one of the longest non-stop U.S. domestic flight routes and the obese man thought he had a spare seat at first but before the door closed, the airline asked a late-boarding passenger weighing 400-pound to sit down next to him in the last empty seat.
Meanwhile, US Airways has also apologised for the inconvenience, which it described as “regrettable", and it offered the passenger a 200 dollar voucher as compensation.
