fat acceptance Southwest Airlines ("the Greyhound of the skies") will start charging fat passengers for two seats. The earliest pieces I saw remained coy on exactly what counts as "fat," but CNN clarifies:

Starting next Wednesday, its "people of size" policy will require passengers who need seat-belt extensions or cannot lower the arm rests on their seats to purchase two seats if they are flying on a plane near or at capacity.

As someone who likes his personal space, this seems like a good policy to me, but the morbidly obese woman that KING-5 News interviewed was outraged ("my weight is private health information!") and threatened a lawsuit. And I did not even know there were "seat-belt extensions," but that's because I've never read the National Association to Advance Fat Acceptance's delightful "Airline Tips for Large Passengers." I can never read stories like this without thinking of the Simpsons episode in which Homer gains weight in order to go on disability:

Manager: I'm terribly sorry, sir, but I'm afraid our facilities are not equipped to meet your needs. Homer: What are you talking about? Manager: What I'm saying, sir, is that a man of your carriage couldn't possibly fit in our seats. Homer: I can sit in the aisle. Manager: I'm afraid that would violate the fire code. Bystander: Hey, Fatty! I've got a movie for ya: "A Fridge Too Far"! [The rapidly-assembling crowd laughs.] Homer: Shame on all of you. Give me my dignity! I just came here to see "Honk If You're Horny" in peace. Manager: Sir, if you'd just quiet down, I'd be happy to treat you to a garbage bag full of popcorn.
