YYC Calgary International Airport Aéroport international de Calgary YYC </sub

YYC Calgary International Airport is an international airport that serves the city of Calgary in Alberta, a province of Canada. Located approximately northeast of downtown, the airport is the fourth-busiest in the country as of 2016, catering to roughly 15.7 million travellers. The region's oil, gas, and tourism industries have helped foster growth at the airport, which has nonstop flights to an array of destinations in North America, Central America, Europe, and Asia. YYC Calgary International is also a hub for two major Canadian airlines, Air Canada and WestJet. Built in the late 1930s, the site has since grown to house four runways, two terminal buildings for passengers, warehouses for cargo handling, and other infrastructure. The Calgary Airport Authority operates the property while paying rent to the federal government. Close to the airport is the Deerfoot Trail freeway for transport into the city, and public transit also serves the airport.
