Yeah I'm with you, flying is what made me really start to hate fatties. I'm pretty tall at 6'4" so flying is uncomfortable enough already, having some butter huffer's rolls spilling onto me depriving me of what little space I have in those cramped seats is enough to make me go insane. I specifically avoid the window seat nowadays (despite it being my favorite like you) so I can at least get up and walk around for a bit every once in a while in case I get seated next to a lardass. I actually had one flight where I was seated next to an elephant of a man, who literally couldn't fit in his seat if I had my armrest down. I complained to a flight attendant about it and got bumped up to first class though, which was pretty sweet.
