NAIAX provides elevated expressway access to all four NAIA terminals and Entertainment City. The expressway runs from the Skyway connection near Bicutan through the airport area to Coastal Road/CAVITEX.
The Skyway to Terminal 3 section serves the busiest terminal (Andrews Avenue area). The Terminal 3 to Terminal 1 section passes through the airport's inner ring. The Terminal 1 to Entertainment City section serves the casino district (Okada Manila, Solaire, City of Dreams).
Traffic patterns are unique, driven primarily by flight schedules rather than typical commuter patterns. The Entertainment City section adds a second traffic peak in the evenings (7-11 PM) that is unlike any other expressway in the Philippines.
