Curaçao has a modern and international airport which can handle all types of aircraft, including Boeing 747’s. The airport handles on average 22,000 flights and more than 1.6 million passengers per year; 13,000 tons of cargo passes through the airport annually. There are daily flights to and from Europe, the U.S., South and Central America and the other Caribbean islands. Various airlines maintain extensive air transportation facilities, both for passengers and air freight. Future plans are to further transform the island into a safe gateway to and from Latin America and other parts of the world by developing a green sustainable, 100% self-sufficient Airport City using green energy innovations such as Saltwater Air Conditioning, Waste to Energy and Ocean Thermal Energy Conversion to generate electricity. Airport City aims to attract business to further stimulate economic growth. Future plans are to offer commercial space travel.
