This is the only comment I intend to make on this: A fat celebrity got in a snit last weekend over his treatment by Southwest. He tweeted about it. Issues of when someone too big to fit into a single coach airplane seat should have to buy two seats are now the most important topic in the world in some media spheres. I think the most important topic involving Southwest today is its plans to start PHL-BOS nonstops, a move that will save customers who need to get to Boston quickly thousands of dollars. But that's just me.
If you want to keep up with the back-and-forth between a celebrity and an airline, just Google it and you will find thousands of references. If you want to know more about airlines and policies for ticketing obese passengers (some carriers have them and others don't), look at this post by farecompare.com CEO Rick Seaney for comprehensive information.
