If you thought paying extra for checked luggage was an insult, you're going to love this.
United Airlines said Wednesday it will enforce a policy to charge overweight passengers for an extra seat.
Passengers who need a seatbelt extender in order to buckle up, or who can't get the armrests down around themselves will have to purchase the extra seat or upgrade to a cabin with larger seating (i.e. first class). If no extra seat is available, they'll have to take a later flight. And if they have connecting flights, they'll need an extra seat or upgrade on every leg of their trip.
If it's any consolation, United said paying for the extra seat would entitle the person to extra carry-on luggage.
The airline said it is enacting the policy for the "comfort and well-being of all customers aboard United flights."
Last year, a Forbes article showed that overweight passengers cost the airlines an extra $538 million a year in fuel. But some have speculated that charging extra for heavier passengers could end in the carrier getting sued for discrimination.
Other airlines reserve the right to charge heavy passengers for an extra seat, but enforcement varies, CBS2 reported. An American Airlines spokeswoman said she doesn't remember ever having to impose an extra charge, but Southwest Airlines started enforcing its policy in 2002.
