I also am a large frame 6' and my legs and my ass dont fit well in a airline seat.
Yes, I could fly 1st class for 4x the price. thats a given, but I'd still have to fly with animals.
Well, I rode my share of greyhounds in the 70s and I have never minded the people next to me on airlines. Truth be told I even hitchhiked on occasion. Obviously, you are from a much higher class of people than I am. I apologize profusely for upsetting your delicate sensibilities.
