I'm 6'5". My flight coming back from Vegas got canceled once and they rebooked me on another flight where I had to sit next to an absolutely enormous bodybuilder who was probably 6'4". Dude's lat was taking up half my seat and I already don't fit in an economy seat. Most miserable flight I ever took.

The main reason I mention this is because this enormous man was doing everything in his power to make himself as small as possible. Every time he'd shift slightly and bump me he'd give me a sincere "Sorry". Dude probably could have eaten me if he wanted to.

My point is the dude sitting next to OP is an asshole, and there is not a single person in here with huge enough fucking balls, or a big enough dick, or a fat enough belly, or big enough muscles, or a large enough FUPA to justify their behavior. Whoever you are, I have seen someone twice your size make it work.
