Last night Kevin Smith decided he was wronged by Southwest Air and took a hatchet to them via Twitter.  Apparently, from his side of the story, he was asked to purchase a second seat ,because of his size, after already being seated.  I have empathy for the embarrassment he may have felt and not being there I can’t say if it was handled properly or not,  but I do agree with the policy of having people who are too large for one seat pay for two.  When I fly with my son, who is still eligible to ride on a lap, I buy a seat for him. Why? Because I feel it is completely inconsiderate to have someone sit next to me and possibly deal with myself or child invading the space he or she paid for.  About two years ago on a flight from Vegas to Philly my wife was stuck next to a woman who put up the armrest and was partly on her seat.  How is that okay?  We paid just as much as that woman yet she was stealing part of the seat we paid for.  Yes she STOLE it.  She did not pay for the space she was using we did.  I understand that this is a delicate thing for airlines to handle and you could easily argue that the seats should be bigger, which would raise fares for every one, but it doesn’t mean that the airlines are wrong to have a policy based on size.  I don’t care about the reason someone is overweight and I do not think any less of them, but it does not give someone the right to take away the space another person has paid for.  The rant Kevin Smith went on last night was understandable, I’m sure he was upset, but just because his feelings were hurt does not make him correct in his argument.
