DENVER - A United Airlines flight of the 787 Dreamliner from Denver to Tokyo was diverted to Seattle Tuesday.
"United flight 139 from Denver to Tokyo-Narita diverted to Seattle due to an indication of a problem with an oil filter. The aircraft landed normally and we are working to reaccommodate customers," United Airlines spokeswoman Mary Ryan explained.
The first Dreamliner flight from DIA to Tokyo Narita took off on June 10. It carried a team of Colorado representatives on a trade mission to Asia, including Denver Mayor Michael Hancock.
The start of the Dreamliner service was delayed several times over concerns resulting from other technical malfunctions, including battery system malfunctions that led to a fire on a 787 parked at Boston's Logan International Airport and a smoking battery that led to an emergency landing by another 787 in Japan.
In April, Federal regulators told U.S. airlines they could fly Boeing's 787 Dreamliners as soon as they replaced its problematic lithium ion batteries.
At 3:32 a.m. Tuesday, United Airlines tweeted, "Today we became the North American launch customer for the Boeing 787-10, ordering 20 of the newest Dreamliners."
