For Visa information and entry
Although the Philippines is an archipelago, most visitors arrive by plane. International airports are located in Cebu, Clark Freeport Zone, Angeles, Davao, Kalibo, Laoag, Manila and Zamboanga.
A much more congenial airport to arrive at is Mactan-Cebu International Airport or Kalibo International Airport , which are both at the centre of the Philippine archipelago and outside the Typhoon belt.
Passengers departing the Philippines have to pay a terminal fee (in addition to the Philippine travel tax levied on locals). This fee is included in airfare if flying from Manila. Otherwise, this ₱550 fee (USD15 if paid in US dollars, Clark is now also ₱550) is paid before entering the immigration and pre-departure “air-side” area of the terminals.
Philippine Airlines (PAL) , Cebu Pacific , PAL Express , Air Asia  Tiger Airways (Tiger Air)  are among the national carriers.
If you plan to travel around the various islands, it is best to get an open jaw ticket. This can save much time back-tracking. Most common open-jaw ticket combinations fly into Manila and out of Cebu. Local airlines also have regular “seat sales”, advertising cheap fares for flights to domestic destinations. However, be aware of travel dates: some tickets booked during a seat sale may only be used on dates well after the duration of the sale (sometimes up to a year after the sale), and advertised fares usually exclude government taxes and fuel surcharges.
If you live in an area with a large Filipino population (such as London, Los Angeles, San Francisco, New York, Hong Kong, Singapore, Taipei or Tokyo), check out travel agencies catering to overseas Filipinos which often have fares keener than those generally advertised.
