Los Angeles International Airport (LAX) in California, US, has invested $1.6bn in security improvements since 11 September 2001, according to a report by Los Angeles Mayor Antonio Villaraigosa.

The security measures include a full-body screening system and an inline baggage handling and screening system to speed up movements through the airport and to check for explosives.

The airport will spend another $36m on expanding its system of 800 closed-circuit security cameras to more than 3,000.

The report was prepared by the Blue Ribbon Panel, which consists of aviation, homeland security and law enforcement experts to assess the airport’s security.
