So much for being in Tokyo by nightfall. At least we are safe and on (the) ground! Enjoy the photo of our Dreamliner dumping fuel over the Pacific.” (Chris Seewald photo)

A Boeing 787 had to make an unscheduled landing at Sea-Tac International Airport Tuesday afternoon because of a problem with an oil filter. 

United Flight 139 from Denver to Tokyo-Narita shortly after 4 p.m. The aircraft landed normally, and United was working to accommodate 210 passengers on board.

Passengers were asked to stay overnight in Seattle and take a 9 a.m. flight Wednesday morning. A passenger on the flight tweeted that the United pilot said the engine was "not operating optimally," and the plane started dumping fuel.

United started the Denver to Tokyo-Narita route on June 10. This story will be updated.
