Nope, this is not unfair nor intolerance. If the plane carries more weight, it has to burn more fuel. While airlines can't (for the moment) weigh passengers checking in, if a person needs two seats to travel then it is a pretty safe bet that they are making a bit more than the average contribution to the plane's weight, and they should pay accordingly.

I had to check my oil on my driving test. (I could do that, but failed for driving too slowly.)
