Clark International Airport is located within the Clark Freeport Zone in the island of Luzon, approximately 98 kilometers (61 mi) from Manila.
The airport serves Central Luzon, Northern Luzon, and, to an extent, Metro Manila with international and domestic flights. The name is derived from the former American Clark Air Base, which was the largest overseas base of the United States Air Force until it was closed and handed over to the Government of the Philippines in 1991.
