United Airlines must defend a proposed class action brought by passengers who paid extra for window seats and boarded to find a blank wall, after a US federal judge threw out the carrier’s argument that the word “window” described a seat’s position rather than its view.

For UK business travellers, who routinely pay seat selection fees on United’s transatlantic services from Heathrow and other British airports, the ruling puts a familiar frustration under legal scrutiny for the first time. Charges for a window or aisle seat on international itineraries can exceed $100 each way, and the case questions what passengers are entitled to expect in return.

US District Judge James Donato in San Francisco denied United’s motion to dismiss the lawsuit on Monday, first reported by Reuters. He found that the airline’s ticketing terms, boarding passes and reservation screens expressly described the disputed positions as window seats when passengers paid to reserve them. “No more is needed at this stage for the breach claims to go forward,” Donato said, according to Reuters.

What passengers paid for

The lawsuit, filed in August 2025, centres on seats aboard certain Boeing 737s, Boeing 757s and Airbus A321s that appear as window positions on the seat map but sit beside an uninterrupted wall panel. The gap is a product of aircraft architecture, with air conditioning ducts, wiring and other systems occupying the space behind the cabin lining.

United argued it had never promised a view. “The use of the word ‘window’ in reference to a particular seat cannot reasonably be interpreted as a promise that the seat will have an exterior window view,” the airline said in its motion to dismiss. The complaint counters: “When consumers choose to book an airplane seat adjacent to the wall, they expect it to have a window.”

The plaintiffs allege United sold more than one million of the disputed seats, with fees ranging from about $45 to more than $160, and seek over $5 million in damages. Only MileagePlus elite members receive free seat selection in economy; all other passengers, including Star Alliance Gold members, pay the fee. The filings also cite a 2017 social media exchange in which United allegedly told a passenger: “Sorry. We never guaranteed you will get a window.”

United said in a statement it updated its website and app in 2025 “so customers can have more information about what to expect when they choose a seat.”

Why the case matters beyond United

A parallel proposed class action is pending against Delta Air Lines in Brooklyn, which Delta is seeking to dismiss. Together the cases could reshape how airlines label and price individual seats as selection charges become a bigger slice of industry revenue. Seat fees have already drawn regulatory attention in the UK, where Ryanair dropped its family seating charge following a Competition and Markets Authority investigation, and the Civil Aviation Authority requires optional extras to be clearly disclosed and offered on an opt-in basis.

The plaintiffs point to American Airlines and Alaska Airlines, which they say warn passengers when comparable seats lack a window, as proof that clearer disclosure is achievable. Attorney Carter Greenbaum, then representing plaintiffs in both cases, told Reuters in November that United’s position was “contrary to the reasonable expectations of countless passengers who unknowingly paid extra money for windowless window seats.” He added: “Consumers deserve better than empty promises and United’s word games.”

The ruling does not establish that United breached its contracts, and the court has yet to decide whether the case can proceed as a certified class. For travellers flying United, including through its Newark hub, the practical advice is unchanged: check the seat map details carefully before paying to reserve.
