A federal judge has ruled that United Airlines must face a class-action lawsuit accusing the carrier of charging passengers extra for "window seats" that lack actual windows due to aircraft design. U.S. District Judge James Donato rejected United's argument that the term "window seat" refers only to a seat's location next to the cabin wall, stating that the airline's own booking screens, ticketing terms, and boarding passes expressly promise a window to customers who pay for one. The lawsuit, filed by passengers seated next to solid walls on Boeing 737, 757, and Airbus A321 planes where air-conditioning ducts block windows, alleges United failed to disclose these windowless seats during booking and seeks millions in damages for over a million travelers nationwide. This decision allows the case to proceed in federal court, affecting passengers who paid premiums for views to reduce anxiety, manage motion sickness, or entertain children.
