Inspired by recent events (and my comment in another thread), a solution for "flying while fat." REQUIRE fats to purchase upgraded seating (absolutely no exceptions whatsoever): At check-in, they should have a template for seats the same as for carry-on luggage. Don't fit in the example seat (any part of you crosses over/under the armrest)?  You must purchase a "fat fare." We're out of fat fares on this plane? Guess you're waiting for another flight, tubby. You should have put the goddamn fork down. Once on the plane, if Crisco McBeetus asks for a seatbelt extender, they are immediately required to deplane. No, they don't get a refund, either. Their fare is now forfeit, and has become a fee for wasting everyone's time and assaulting their senses. Seriously, the standard seat belts have PLENTY of reach, even for fat fucks. If they need more, they're a safety hazard, and should go by freight train instead. Basically, it should be made as embarrassing as possible to fly while fat. From check-in to leaving the plane, fats should be reminded of how much of an inconvenience (and potential hazard) they are to the crew and the rest of the passengers.
