The cause is still under investigation for Tuesday's emergency landing in Seattle of a Denver-to-Tokyo United Airlines 787 Dreamliner, but the 210 passengers on the diverted flight took off Wednesday morning for Tokyo aboard another 787 aircraft.

"It was on a different aircraft, but still a 787," said Mary Ryan, United spokeswoman. "The aircraft from (Tuesday) is still in maintenance in Seattle."

The 219-seat Dreamliner left Denver International Airport midday Tuesday and turned back for Seattle-Tacoma International Airport after the pilot received indictation of an oil filter issue.

Ryan said that the passengers were provided hotel lodging overnight and that all of them, as far as she knew, took the next-day flight to Narita International Airport.

"We heard that the passenger reaction was good. Usually when we get a change of aircraft or diversion we will get a customer reaction survey and we didn't hear anything negative," Ryan said.

Ryan reiterated that "this isn't something specific to 787, it is just a standard maintenance issue."

Kate Bergman, a spokeswoman for the plane's manufacturer Boeing, said the company has been working with United and General Electric, the airplane's engine manufacturer, "to complete the appropriate maintenance acitivites and return the aircraft to service."
