SWA really needs to ease up. The responsibility should be with ticket counter and gate agents, people don't deserve to be humiliated by a plane full of people.
The fact that he few up to from Burbank without any problem reminds me what a lawyer told me one time, "It's better to not have a policy at all then a policy that followed only once in a while"...
I know that SWA is a very low cost carrier and I'm sure Kevin could have afforded a second seat if they had told him AT THE GATE or CHECK IN.
If SWA is so cheap they can't give a passenger of size an extra seat every once in a while, they need to have a seat at the gate and have questionable pax sit in it BEFORE they get on the plane.
The airlines must be unaware that obesity is now seen as a medical condition and ADA rules are soon to follow....
It's very sad, but it takes a large celebrity to expose the problem....
