The Ninoy Aquino International Airport or NAIA, also known as Manila International Airport, is the airport serving Manila and its surrounding metropolitan area. Located along the border between the cities of Pasay and Parañaque, about 7km south of Manila proper and southwest of Makati, NAIA is the main international gateway for travelers to the Philippines and serves as a hub for AirAsia Philippines, Cebgo, Cebu Pacific, PAL Express, and Philippine Airlines. It is managed by the Manila International Airport Authority (MIAA), a branch of the Department of Transportation (DOTr).Officially, NAIA is the only airport serving the Manila area. However, in practice, both NAIA and Clark International Airport, located in the Clark Freeport Zone in Pampanga serve the Manila area, with Clark catering mostly to low-cost carriers because of its lower landing fees compared to those charged at NAIA. In the recent past there have been calls for Clark to replace NAIA eventually as the primary airport of the Philippines. The airport is named after the late Senator Benigno "Ninoy" Aquino, Jr., who was assassinated at the airport in 1983. In 2015, all terminals at NAIA handled a record breaking annual passenger traffic of 36,681,601, domestic passengers totaled 19,513,514 compared to international travelers, totaling 17,168,087.
