Inside NAIA or Ninoy Aquino International Airport. 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 Angeles, Pampanga serve the Manila area, with CIA catering mostly to low cost carriers that avail themselves of the lower landing fees than those charged at NAIA. In the long term CIA is set to replace NAIA 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.
