quote: I heard this discussion on the radio the other day and many people were saying that it's not fair to heavy people.
quote: There are also weight limits on airplanes and typically the smaller airplanes are the only ones we notice issues with weight.
quote: It certainly could get off the ground,
quote: BMI is irrelevant - you're trying to introduce some kind of "morality" into the equation...the notion that the 7' man is "morally correct" in his weight, wheras the 4'11" girl is "morally incorrect" in her weight.
quote: If the purpose was specifically to address obesity then they would be using BMI for pricing.

quote: They could even put bigger seats in some of the rows on the plane and charge more for them.
quote: But they should then be given wider seats for what the paid extra in any class, not just in business.
quote: Because it literally - LITERALLY - costs the airline twice as much to provide the service to that person.
quote: Looking at the Boeing 767-400, operating empty weight is 229,000lbs and max take off weight is 450,000lbs giving about 220,000lbs of cargo and passenger weight.So the actual percentage increase in fuel costs if you double passenger weight, assuming fuel costs are linear with weight ( it isn't, 1% reduction in weight only gets you a 0.75% reduction in fuel use), is ((450,000/(229,000+110,000))-1)*100= 33%.
quote: It makes more sense to distribute the cost of the plane's weight on a per pound of payload basis. Your 767 has a maximum payload of 220,000. The 300 pound person consumes 0.136% of that. The 150 pound person takes 0.068% of that. And they should pay accordingly.
quote: families with young children could pay much less than what they're paying now
