Alaska Airlines Passenger Threat Triggers Seattle Airport Runway Shutdown, Flight Delays

Seattle-Tacoma International Airport experienced significant disruptions after a passenger aboard Alaska Airlines Flight AS2123, operated by Horizon Air, issued a direct threat to the safety of the aircraft during taxiing before takeoff. The threat, reportedly a bomb threat though details remain undisclosed, prompted the crew to secure the plane on a runway away from the terminal, leading to the evacuation of all 68 passengers and four crew members. Law enforcement and emergency teams responded swiftly, surrounding the aircraft, taking the suspect into custody without incident, and conducting thorough security measures including searches and passenger screenings. Two major runways were closed during the incident, resulting in a ground stop issued by the FAA, cancellation of at least six flights, and diversion of two others, causing widespread delays. The affected aircraft will remain out of service pending completion of enhanced security protocols, and investigations into the incident are ongoing. Authorities continue to prioritize security as they assess the situation and resume normal airport operations.
