Taxi service is available to NAIA from all points of Metro Manila. Also, several bus routes directly serve the airport complex, either serving Terminals 1 and 2, Terminal 3 and the Domestic Terminal, or Terminal 3 exclusively. Some of the bus routes are also served by jeepneys. A shuttle bus system connects all four terminals for the convenience of passengers who have onward connections on flights departing from another terminal. The airport is also accessible, albeit indirectly, by rail: Baclaran station of the Manila Light Rail Transit System and Nichols station of the Philippine National Railways both serve the airport complex.
In the future, with the extension of the existing Yellow Line, a new station, Manila International Airport station, is set to connect the airport, albeit still indirectly, to the LRT. The NAIA Expressway or NAIA Skyway connecting NAIA/Sales Exit of Metro Manila Skyway and Andrews Avenue in front of Terminal 3. Terminal 3 is served by Sales Exit of South Luzon Expressway and the NAIA Road-Roxas Boulevard Intersection of Coastal Road serving Terminals 1 and 2 and Domestic Terminal.
