Not really "thinking outside the box"- more like an excuse to pick on the overweight, and the PC police (PC Police being defined as anyone who is more sensitive than yourself.).

Our current pricing system is based on supply and demand- like everything for sale in a capitalist society. We sell a block of space in a tube that moves people from one place to another. As long as you fit in the block, it doesn't matter what you weigh. Passenger airliner payloads are limited by volume, not weight. You guys are arguing as though the airlines are losing money because people are too fat. Yes, the plane burns more fuel if it is heavier, but we pass that cost on to the customer, and it's only a small part of the overall cost of running an airline anyway.

If you're running an with small planes that tend to be limited by weight rather than volume, and you can't sell all the seats because you're customers are too big, then maybe a policy like this makes some sense. Otherwise, why is it even being discussed?
