The Ninoy Aquino International Airport (NAIA) will undergo scrutiny by the United States-Transportation Security Administration (TSA) this week as part of the regular security assessments of airports whose airlines have routes to United States. The inspection is in connection with the observance of safety standards set by the International Civil Aviation Organization (ICAO). The review will cover procedures involving perimeter and terminal access control; facility security; screening; cargo operations; and aircraft security. Manila International Airport Authority assistant general manager for security and emergency services, Vicente Guerzon, said airlines operating out of the NAIA with flights to the United States have been reviewed by the US transport agency last week. Participating carriers include Philippine Airlines, Cebu Pacific Air, Delta Air Lines, United Airlines, Eva Airways, Federal Express, and United Parcel Service. In May last year, the TSA assessment results showed that security procedures at the NAIA are up to standard.
