(PORTLAND) -- The crew of a Delta Air Lines flight bound for Portland, Ore., discovered what law enforcement sources say were "three to four" box cutters.
Authorities met the aircraft on arrival, at the request of the flight's crew. A Delta spokesperson said all passengers were deplaned without incident and that the airline is cooperating with the investigation.
Flight 90 originated in Seoul, South Korea, before stopping in Tokyo, where it departed for Portland International Airport.
