Eight Southwest Airlines and US Airways flights were delayed out of Los Angeles International Airport (LAX) Sunday morning, June 24th, after two unrelated incidents in Terminal 1.

The passenger screening checkpoint in Terminal 1 was temporarily closed at about 10:40 a.m. after a female passenger reportedly failed to wait for a secondary screening by Transportation Security Administration (TSA) workers, airport officials said.

Airport police searched for the passenger in the concourse and, after she was located, TSA employees completed the screening process without incident, airport spokesman Marshall Lowe said.

Approximately ten minutes later, at 10:50 a.m., the head of a fire sprinkler popped off in the east end of Terminal 1, near the Southwest Airlines ticketing area on the upper level, Lowe said.

Some passengers were sprayed with water but it was unclear how many, Lowe said.

The Los Angeles Fire Department was called to the scene and workers repaired the broken sprinkler.

Passengers in the terminal area were evacuated to the curb outside while workers mopped up the water, Lowe said.

The cause of the sprinkler head malfunction is under investigation.

Terminal operations returned to normal by 12:30 p.m.
