Why don't airlines charge by a customer's weight?
But isn't it fairer to charge based on weight since heavier passengers take up more fuel and thus cost more for the flight?
While it's true that heavier passengers may require more fuel, airlines typically factor in the weight of passengers and baggage when calculating the weight of the plane for safety reasons. Additionally, charging by weight could create logistical challenges for airlines when it comes to booking and departure processes.
