Americans have gotten fatter, and that’s making a big difference for airline operations. Each aircraft has a maximum weight it can take off with, and the weight of passengers and cargo contributes to how much fuel a plane is going to burn on a trip.
American Airlines this week updated its passenger weight assumptions. That’s going to mean they need more fuel for some trips. It even means that some aircraft will be ‘weight restricted’ and not allowed to carry a full load of passengers and cargo.
