I'm not a big guy, but I say, yes. It's ridiculous how airlines have squashed passengers into planes like sardines in a can.
It's not your imagination. Airline seats are shrinking.
A wave of air-rage incidents has exposed the problem like a threadbare economy class seat on an aging puddle jumper. A Delta Air Lines flight from New York to Palm Beach, Fla., recently made an unscheduled landing in Jacksonville after two passengers scuffled over a reclining seat. It followed two similar altercations a few days earlier, both of which also involved seat-related altercations.
