Subic Bay International Airport serves as a secondary and diversion airport for Ninoy Aquino International Airport in Metro Manila and Clark International Airport in Pampanga. It also serves the immediate area of the Subic Bay Freeport Zone, the provinces of Bataan and Zambales, and the general area of Olongapo in the Philippines.
The airport was, as is the Naval Air Station Cubi Point, part of the Subic Naval Base of the United States Navy, before the base closed.
