United Airlines delays DIA to Tokyo flight again due to 787 safety investigation

DENVER - United Airlines is once again delaying its plans to fly a nonstop flight from Denver International Airport to Tokyo, Japan because of issues with the Boeing 787 Dreamliner.

The airline issued a statement Friday that said, "We are further postponing the launch of our new route from Denver to Tokyo-Narita while the FAA and Boeing work to certify a solution for the 787 aircraft. We are currently revising the route initiation date to June 10, although that will depend on having a successful resolution ahead of that date."

United announced last May that it planned to begin the nonstop service on March 31, 2013. Fares starting at $980 roundtrip were even posted on United's website.

United planned to operate the service with the new Boeing 787 Dreamliner aircraft that was grounded earlier this year because of battery problems and safety concerns.

Because the plane was grounded, United initially delayed the Denver to Tokyo flight to May 12. Now it's being delayed another month.

DIA has nonstop flights to Europe, Mexico, Canada and Costa Rica, but not to Asia.

"Our focus remains steadfast on strengthening the economic and cultural connections between Denver and Tokyo," said Denver mayor's spokeswoman Amber Miller.

Mayor Michael Hancock said last year that the new flight will generate more than $130 million in annual economic benefit to Colorado.
