It would be interesting to come up with a way to control with whom you’re sitting instead of just where you are sitting on your upcoming flight. Maybe instead of choosing aisle or window, you could choose to sit next to a talker or maybe a sleeper, college grad or undergrad, art major or business major, vegetarian or carnivore. At least make a maximum butt width for an entire row. Why have rows which are 110% butt-full, and some which are 90% butt-full? The guy next to me is gigantic … Just his shoulders … and there are two teeny women and a frail senior sitting in the row behind us.
