JetBlue on Sunday confirmed a security concern with a flight that arrived at Sea-Tac Airport.
Sea-Tac said they were investigating a security concern with Jet-Blue flight 1006 "out of an abundance of caution." The flight landed safely from Long Beach.
One passenger sent KING 5 a picture saying the captain announced on the plane that there was a threat specific to that flight. She said at one point police had surrounded the plane.
One-hundred-fifty passengers were being transported to the terminal by bus.
Sea-Tac officials said police would continue to investigate.
There was a separate threat against a Delta flight that landed in Seattle after a flight from Phoenix.
Northwest Cable News executive producer Jenna Luthman was on aboard Delta flight 4741. She said the pilot told passengers there had been a threat against the plane.
"He said in his whole pilot career he's never experienced anything like this before, and he said that three planes all had separate bomb threats coming in to Seattle, and it was a JetBlue flight and another one ahead of us and our flight as well, and he said there might have been a fourth," she said.
Also, a Delta flight from Los Angeles to Orlando was diverted to Dallas.
Just before 6 p.m. Sea-Tac officials said the two planes were cleared and were returning to their gates.
