Piarco International Airport — Port of Spain, Trinidad and Tobago

Trinidad's main air gateway takes its name from Piarco, the district east of Port of Spain where the airport, coded POS, was built during the 1930s on land once used for horse racing and breeding. As the busier of the two islands making up Trinidad and Tobago, Trinidad channels substantially more traffic through POS than the smaller airport on Tobago receives, and POS serves as the primary hub for Caribbean Airlines. The country's energy sector, built on offshore natural gas and petrochemical production, drives a steady flow of business travel through the airport, supplementing tourism and the seasonal surge tied to Trinidad's famous Carnival celebrations each year. Regional routes connect POS to numerous other Caribbean islands, while longer flights reach North America and parts of Europe. The airport underwent significant terminal expansion around the turn of the millennium to accommodate rising passenger numbers.
