Cost-cutting carriers are considering weighing passengers in an effort to reduce wasted jet fuel.
The practice would help airlines save billions, at the cost of a little embarrassment for passengers.
It's something that airlines already do, in an unscientific way.
Earlier this year The Independent reported on the costly and inaccurate method of predicting air fuel using an "assumed weight" for passengers.
Allowing fuel spend to assume that male passengers weigh 88kg, women 70kg and children 35kg, the airlines try to reduce the cost of lugging excess fuel around the world.
