United Airlines To Charge Heavier Passengers Twice To Fly - cbs2chicago.com
Under the rules outlined by United, passengers who "are unable to fit into a single seat in the ticketed cabin; are unable to properly buckle the seatbelt using a single seatbelt extender; and/or are unable to put the seat's armrests down when seated" will be denied boarding unless they purchase an extra seat.
If no empty seat exists, the passenger will be forced to take a later flight.
"The seat purchase or upgrade must be completed for each leg of the itinerary," the United policy states. "If a customer meeting any of the above-listed criteria decides not to upgrade or purchase a ticket for an additional seat, he or she will not be permitted to board the flight."
