San Diego Airport Lockdown Today: Passengers at San Diego International Airport faced major delays and confusion Thursday after police activity at Terminal 1 triggered heightened security measures and temporary disruptions near TSA screening areas.
According to reports shared by travelers at the airport, the incident began after an individual allegedly ran through a Transportation Security Administration checkpoint without authorization, prompting an immediate response from airport security personnel and law enforcement officers. Witnesses described scenes of gridlock and long lines forming near Terminal 1 as authorities worked to secure the area and investigate the situation.
Social media posts from passengers inside the airport showed crowded security checkpoints and stalled lines as travelers waited for updates. One traveler wrote, “Layover delay since someone at the San Diego Airport ran thru the TSA security,” while another shared a “live look” at heavy congestion near the Terminal 1 TSA area.
Officials have not publicly confirmed all details surrounding the incident, including whether any arrests were made or whether the individual was successfully located. However, airport operations in portions of Terminal 1 were reportedly slowed significantly as officers conducted security procedures out of caution.
The temporary disruption created frustration for many travelers already dealing with busy airport traffic. Some passengers reported extended wait times, missed connections, and confusion over changing security instructions. Airport staff and TSA personnel were seen directing travelers and attempting to manage growing lines throughout the terminal.
San Diego International Airport, one of the busiest airports in Southern California, frequently experiences heavy passenger volume, particularly during peak travel periods. Security incidents involving TSA checkpoints often lead to immediate operational slowdowns because officials must ensure that all secure areas remain protected and that no threat exists to travelers or airport employees.
Authorities continue investigating the circumstances that led to the security breach. Travelers heading to San Diego International Airport have been advised to allow additional time for screening and to monitor airline and airport updates for possible delays.
As of Thursday evening, airport operations were gradually returning to normal, though some residual delays were still being reported at Terminal 1.
