All international flights in and out of Manila use one of the three main terminals of Ninoy Aquino International Airport in Manila's south, while many domestic flights use a fourth, domestic, terminal. The four terminals share runways, but they are not particularly close to each other. ‘Airport Loop’ shuttle vans (P20, 7am to 10pm) link the four terminals, but it's slow and sporadic, so take a taxi if you're in a hurry.
At the time of research the P550 departure tax for international departures out of NAIA was set to be integrated into the airfare, so you won't have to pay at the airport.
Take note that several Asian discount carriers fly to Clark International Airport (Diosdado Macapagal Airport, DMIA) in the Clark Special Economic Zones, a two-hour drive north of Manila.
The main domestic carriers are PAL Express (PAL) and low-cost carrier Cebu Pacific. Tigerair Philippines and AirAsia Zest are also popular.
