Movie director Kevin Smith, known for the witty and obscene dialogue in movies he’s penned like Clerks, Chasing Amy and Dogma, was deemed a flight risk by a Southwest airlines pilot last weekend and ordered off the plane.

"I know I’m fat, but was Captain Leysath really justified in throwing me off a flight for which I was already seated?" he ranted through his Twitter account to over 1.6 million followers.. "Again: I’m way fat… But I’m not THERE just yet. But if I am, why wait til my bag is up, and I’m seated WITH ARM RESTS DOWN.”

Smith posted this pic of himself (above, right, exactly as shown) puffing out his cheeks and captioned it, "Look how fat I am on your plane! Quick! Throw me off!"

Another emerging issue on airplanes is those travelling with small pets.

An editorial in the current issue of the Canadian Medical Association Journal notes that air travel has become increasingly difficult, with tightened security restrictions and a decreased number of services. But now Air Canada is adding to the difficulty by allowing small pets to travel airplane cabins.

Pets can be accommodated comfortably and safely in airplane cargo holds, which is where they belong. Airlines must choose to put the needs of their human passengers first, or be forced to do so.

Flying should not include avoidable health risks, especially, for passengers with allergies to pets. Many people with allergies to animals will have a reaction when they’re trapped in an enclosed space, often for hours.

The Canadian Transportation Agency ruled that people allergic to nuts should be considered to have a disability under the Canada Transportation Act and must therefore be accommodated. The agency is now receiving passenger complaints about pets on airplanes and considering whether those with allergies to pets should also be considered as having a disability. Such a finding would force Canadian airlines to safeguard passengers with pet allergies.
