I do not think the actual different is much unless the person is really overweight or underweight. And because of so much additional investment in to infrastructure and training required, it is pretty stupid to actually implement the idea. That said, it will be bad argument to say that it will punish the people for more weight, because at current price they are actually punishing underweighted and have them pay for the overweighted. ( poor fellas, they are underweighted and have to pay for it too. )
