United's next decision: What to do with all those Boeing 737 Max 10 seats it ordered years ago

United Airlines now has a new question to answer: what to do with the Boeing 737 Max 10 interiors it ordered years ago. The carrier wanted to install lie-flat premium seats on the Max 10 once certified, but certification has been delayed for years and United has shifted to outfitting other aircraft. CEO Scott Kirby told CNBC that United will have to decide what it wants for the Max 10 cabin when the planes are finally cleared. Kirby said the airline has “a bunch of lie-flat seats” that don’t fit other airplanes. United expects the first Max 10 deliveries in summer 2027 and has 167 on order.
