Travelers at San Diego International Airport experienced major disruptions Thursday after police activity near Terminal 1 triggered heightened security measures and temporary delays throughout the airport. Reports from passengers and witnesses indicated that the situation began when an individual allegedly bypassed or ran through a TSA security checkpoint, prompting an immediate response from airport police and Transportation Security Administration officers.
According to social media posts and traveler accounts shared online, security operations at Terminal 1 slowed significantly as authorities worked to secure restricted areas and determine whether any threat existed to passengers or airport employees. Long lines quickly formed near TSA screening checkpoints, while some travelers described confusion and gridlock inside the terminal as airport personnel redirected passengers and adjusted screening procedures.
Witnesses inside the airport described scenes of frustration and uncertainty as hundreds of passengers waited for updates. Several travelers reported concerns about missing flights or connecting departures because of the delays. One passenger wrote online that their “layover delay” began after someone allegedly ran through airport security, while videos posted from inside Terminal 1 showed crowded waiting areas and backed-up security lines.
Authorities have not publicly confirmed all details surrounding the incident, including whether any arrests were made or whether the individual involved was located immediately after the breach. Officials also have not indicated that there was any direct danger to travelers, but airport police treated the matter seriously as a precaution while conducting security checks throughout portions of the terminal.
The disruption comes as Terminal 1 at San Diego International Airport continues to handle heavy passenger traffic following recent modernization and expansion efforts at the busy Southern California travel hub. Airport officials have encouraged travelers to arrive earlier than usual and monitor airline updates closely whenever security incidents or operational delays occur.
By later Thursday evening, operations at Terminal 1 were gradually returning to normal, although some residual delays were still being reported. Airport staff and TSA officers remained visible throughout the terminal assisting travelers and helping restore normal screening procedures. Investigators continue reviewing the circumstances surrounding the incident to determine exactly how the security breach occurred and whether additional measures may be needed to prevent similar disruptions in the future.
