United Airlines again delays Denver-Tokyo flights

Denver: United Airlines is again delaying the launch of a new route from Denver to Tokyo-Narita airport while US regulators investigate problems with the new Boeing 787 aircraft.

The airline said Friday it now hopes to begin the route on June 10, but that will depend on getting the aircraft in service.

Federal officials are still trying to determine what caused problems with the new jetliners’ batteries.

Denver officials say they’re confident the flights will benefit the city, the metro area and the Rocky Mountain region.
