For those of you who voted "NO" would you also approve of two extra-small passengers (i.e. my wife and I) paying for only ONE ticket for the both of them if they both fit in one seat?
To be honest... I'd be surprised to see two normal sized human beings who can fit in one airline seat. Even two little kids would have a tight fit. And I think this wouldn't be allowed simply for safety reasons. One seat = one set of safety/lifesaving equipment, which means in the case of an accident, only one of the two people would have a life-vest, breathing apparatus, etc.
Being somewhat large myself, it isn't as if we are trying to inconvience others when we travel. I do my best to stay out of other people's way and I don't take up more than one seat. I don't want someone taking one look at me and judging that I'm too 'large' and therefore must by a second seat when I don't need one and fit just fine in the existing seats.
Weighing by the pound doesn't necessarily work either. I have a friend who is quite tall and weighs well over 300+lbs, but he isn't wide by any means, just tall and muscular. As long as he fits in the seat, he shouldn't have to pay extra for it. However, I've seen short women who have hips that look like hoola-hoops. They probably weigh less than I do, but their 'build' makes it more difficult to fit into those sorts of seats. I've even seen non-obese people who just have the 'pear' bodytype and happen to be wider in the bottom have trouble that has nothing to do with being fat.
Perhaps there isn't an easy answer to this, but I don't think people should have be forced, at the airport, after making their plans and possibly spending quite a bit of money, to pay an additional fee for a seat that they were not expecting. It could ruin a person's entire vacation and it simply isn't a feasible idea
