Should airfare ticket prices be based on weight?
From a pure standpoint of economics it would be fair. The weight of the cargo profoundly effects the amount of fuel consumed. If an airplane has a capacity of 200 passengers then their weight makes a huge difference in what the cost to the airline for fuel is. 200 people weighing 120 lbs totals 24,000 Lbs. If they weigh 150 lbs then it is 30,000 lbs. If they weigh 200 lbs then it is 40,000. At 250 lbs people make it 50,000 and 300 pounders would result in a weight of 60,000 lbs. The fairest way to charge would be to do it by weight of the passenber, the carry on items (much less these days) and the checked baggage. I am not trying to be unfair to anybody, but it is basic math, physics and economics.
