What is the Airside Shuttle Bus in Manila International Airport, NAIA?
Airside Shuttle Bus - Provided by
NAIA airport, these buses transfer passengers through internal roads to
terminals 1, 2, 3, and 4 - free of charge. It operates 24/7 and runs every 15 minutes. You can find the “Shuttle buses pick-up passengers/drop-off point” at the ramp area on each terminal.
To cut down the time of transfer, these buses use the
internal road inside the airport complex for passengers who have connecting flights departing from another terminal. Before riding the airside transfer shuttle, it is a must to clear the
Immigration and Customs first. Note also that the shuttle bus has a distinctive white colour.
This is what I used T3 to T1 at 2am in the morning. Took 25 mins including a long stop to drop off passengers and pick up nobody at T2.
