Two F-15 fighter jets were scrambled to escort an Alaska Airlines flight from Kona, Hawaii to Sea-Tac Airport in Seattle after someone reportedly told the FBI there was a hijacker on board the plane.

FBI spokesman Tom Simon told the passenger who was reported to be a hijacker by the caller has been cleared and released after questioning.

The threat was called into the FBI’s Honolulu office Thursday afternoon and the bureau subsequently informed other agencies and local authorities in Seattle of the call, Simon said, adding that the passenger in question did not show any unusual behavior on the flight.

Flight 819 landed at Sea-Tac without incident shortly after 7 p.m. PST and the FBI detained and questioned a passenger who reportedly had slept through most of the flight.

The FBI finished interviewing the passenger late Thursday and an FBI spokeswoman told the Associated Press the agency was "not anticipating an arrest."

"If this turns out to be hoax phone call the FBI in Honolulu will take this very seriously," Simon told

An investigation into the phone call is ongoing.
