Security was heightened Thursday at Los Angeles International Airport in response to the crash of an Egyptair flight but San Diego's airport reported no change in security measures.
Egyptair Flight MS804 was carrying 66 people. A top Egyptian official said it was more likely the jet was downed by a terror attack than technical problems.
LAX officials did not provide specifics, but said the "security posture" and "counter-terrorism security measures" have been stepped up at Los Angeles World Airports-controlled airfields.
San Diego International Airport, also known as Lindbergh Field, has not received a directive from the TSA to change security measures, San Diego Airport spokesperson Rebecca Bloomfield told NBC 7.
"As always, we encourage passengers to be vigilant when traveling through the airport and report any suspicious activity or behavior to the proper authorities," Bloomfield said.
Egyptair Flight 804 was an Airbus A320 carrying 56 passengers and 10 crew members. It went down about halfway between the Greek island of Crete and Egypt's northern coastline after takeoff from Charles de Gaulle Airport.
Egypt's aviation minister says it may have been a terrorist attack. There are no immediate signs of any survivors.
Those on board, according to Egyptair, included 15 French passengers, 30 Egyptians, two Iraqis, one Briton, one Kuwaiti, one Saudi, one Sudanese, one Chadian, one Portuguese, one Belgian, one Algerian and one Canadian.
