An Alaska Airlines flight bound for San Francisco was diverted to Portland, Oregon, after a jump seat passenger inside the cockpit attempted to disable the aircraft engines.
Alaska Airlines Flight 2059 operated by Horizon Air from Everett, Washington, diverted on Sunday after reporting a credible security threat, Alaska said in a statement.
The Federal Aviation Administration told airlines in a notice seen by Reuters the individual sought to disable the engines on the Embraer 175 regional jet by deploying the fire suppression system and added the crew was able to subdue the individual and remove him from the flight deck.
