United Airlines delays Denver-Tokyo flights
United Airlines is delaying the launch of a new route from Denver to Tokyo-Narita airport while U.S. regulators investigate problems with the new Boeing 787 aircraft.
The airline said Thursday it now hopes to begin the service on May 12, but that will depend on getting the aircraft in service.
In the meantime, United Airlines is taking the troubled Boeing 787 out of its flying plans for the rest of this month.
Federal officials say it could be weeks before they know what caused a 787 battery fire last month.
