The original air facilities in Kochi were an aerodrome and airstrip on Willingdon Island, built in 1936 by the British Residency of Kingdom of Kochi, intended for transporting British officials involved in the development of Cochin Port. The airstrip was converted into a military airport by the Royal Indian Navy during World War II. The Royal Navy chose it as a strategic site for their headquarters in Southern India and as an air station cum landing craft and sea plane base. After Indian Independence, the Indian Navy operated the airport, though it permitted civilian aircraft to use the facility. The Gulf economic boom of the 1980s made it necessary to develop international transportation to Kochi in the interests of expatriates working in the Middle East.

Cochin International Airport is the first in India developed under a public-private partnership (PPP) model.
