I support this, but I also think airlines have a responsibility to stop shrinking seats. It shouldn’t be a contest to see how many more seats can be fit onto the airplane. Give us normal sized, comfortable seats as the standard.
It’s ridiculous that seating is so tight that there is no way for me to be comfortable for any significant flight and it’s miserable for anyone other than a child around me.
Whenever I can, I fly in a premium cabin. But if that’s not an option, I’d rather drive 7-10 hours than fly economy.
There is a problem with heavily obese people taking up significantly more horizontal space than is actually fair, but it's absolutely compounded by the airlines shrinking the per-passenger space to the size of the average passenger.
I've been on trains in a half dozen countries, the back of a police car (for business purposes), a donkey, bulldozer, dozens of different venues (theaters, arenas, etc) and various farm tractors. All are more comfortable, except for a stadium seat where i had to straddle a beam.
