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

United Airlines is deciding what to do with the Boeing 737 Max 10 seats it ordered years ago. The airline originally planned to install lie-flat premium seats on these planes once they were certified, but certification delays have pushed back that timeline by years. The company now faces a strategic decision on how to proceed with the aircraft and its premium seating plans.
