Commuting from NAIA Terminal 3 is quite easy and cheap compared to Metered Taxi, it's just a little patient needed because of the limited shuttle bus going out and going in. The first thing to do is to secure all your belongs before to exit the terminal, you can see the airport loop on the right side of the exit door of the NAIA terminal 3. The second thing to do is to fall in line, but make sure to ask first the airport loop staff about where the bus going to because there is also a bus going to inter-terminal route, Terminal 1 , Terminal 2, Terminal 4.
