The General Santos International Airport is located in Barangay Fatima in General Santos City. The airport, also referred to as the GenSan Airport by the locals, began commercial operations in 1996. When it opened, it was the biggest airport facility in Mindanao, occupying 600 hectares of real estate. It was built largely on grants from the United States through the United States Agency for International Development. The General Santos International Airport replaced the old Buayan Airport, which is now used by the Philippine Air Force as a satellite station. The airport serves as a primary gateway for the SOCSARGEN (South Cotabato, Saranggani, and General Santos) region. The newly built airport considered as one of the best airports in the country due to the panoramic view of Mount Matutum on its background, a glimpse of the city on one side and the clear blue waters of Sarangani Bay on the other side. It has an attractive terminal building with landscape grounds.
Cebu Pacific flies to General Santos three times a week from Manila and once a week from Cebu International Airport, while Philippine Airlines has daily flights out of General Santos Airport going to the Ninoy Aquino International Airport in Manila. AirPhil Express, on the other hand, flies once a week from Manila.
