"I am not small fry myself at 5'10" 230 lbs, but I had the unfortunate experience of being next to the largest human I have ever seen on an airplane. It was on a CRJ too. 350-400 lbs, 6 foot 7, about as wide, this had to be the starting offensive lineman for some professional team somewhere. Not just fat either, just a HUGE human being. "


I think I sat next to that guy on an SFO-LHR trip on a 777 in E-. Sold out plane, no other seats available :-( FA took pity on him at the end of the flight and let him sit in a crew rest seat for landing.
