Airport officials said they were rescreening passengers at terminal 1 "out of an abundance of caution." The concern was that during Wednesday's power outage, there was the possibility that some passengers and bags were not screened.
LAX UPDATE: @LAAirportPD is clearing Terminal 1 before TSA re-screening can begin. When the terminal has been cleared, we estimate it will take one hour to re-screen passengers. @SouthwestAir guests should check flight status w/airline and allow extra time #LAXalert— LAX Airport (@flyLAXairport) June 6, 2019
This process triggered long lines for travelers, who were already frustrated due to previous delays and cancellations. The TSA checkpoint has since returned to normal operations, and lines have diminished.
