I was on a Charter flight down to Fuerteventura a few weeks back with a fairly big guy sat in front of me. I didn't have a problem with it, and I know Charter Airlines don't have alot of seat pitch.
Just after takeoff he was obviously uncomfortable and decided to try and make himself more comfortable by bouncing around his seat - The seat kept swinging back, then 10 minutes later he reclined his seat and it broke, so the seat was practically touching my face for the rest of the flight. To say annoyed was an understatement. I paid for my seat, I don't expect some fat fella who obviously has no respect at all to make my trip as uncomfortable as possible while he enjoys his.
I have nothing against fat people, but some of them should have some respect for others instead of thinking of themselves all the time.
