European carrier Finnair is now weighing passengers at the gate before they board the plane as a way to estimate how much the jet will weigh at takeoff. But it's not mandatory.
The majority of costs to the airline are in taxes, airport fees, and lease costs of the plane. I think you’ll be surprised to find out that fuel consumption is a very minor part of the ticket cost. You must also consider that the increased fuel consumption of +50kg of extra cargo to a system that is 100+ tons to begin with is going to be a bit negligible.
Sure you could have a progressive weight charge. But it’s gonna be more like $1 for someone who is twice your weight. Not twice the ticket price.
