If everybody had their own little plane to fly, the overweight person would end up paying more for the same trip because of the higher fuel cost. That person is simply more expensive to transport. Now, you can claim that we shouldn't expose people to the humiliation of being weighed at the airport and I agree with that and thus, it might just be best to divide the added cost among the passengers like we do today. But apart from that, the fairness argument seems deeply flawed to me. I guess that I am quite the capitalist (even though I'm from Scandinavia) but it doesn't seem fair to me to force the other passengers to share that persons extra cost.
