If you pay extra for a “window” seat, you expect an actual window. But lawsuits against Delta and United claim the airlines charged millions of customers extra to switch to window seats that faced nothing but a blank wall.

Why? The layouts of certain airplanes—Boeing 737s, Boeing 757s, and Airbus A321s—don’t always match up with the seats. In those spots, passengers sit against ducts or conduits instead of a window. The airlines might shrug and say, sorry not sorry. But for many passengers, that’s not good enough.

Other airlines don’t stiff passengers on window seats

Here’s the catch: Alaska Airlines and American Airlines already flag which seats don’t have windows. They show that info on their booking pages. The lawsuit argues it’s 2025—Delta and United could easily do the same.

Some might argue you could check SeatGuru before booking. Lawyer Carter Greenbaum shot that down. “A company can’t misrepresent the nature of the products it sells and then rely on third party reviews to say a customer should have known that it was lying.”

Greenbaum’s firm filed two lawsuits on August 19. It’s taking on United in San Francisco federal court and Delta in Brooklyn. The suits argue, “Had plaintiffs and the class members known that the seats they were purchasing (were) windowless, they would not have selected them — much less have paid extra.”

The lawsuits name individual plaintiffs, but they want damages for more than one million customers. If you bought a so-called window seat and spent the whole flight staring at a wall, you’ll want to follow this trial.
