St. John's International Airport (YYT) is the principal commercial airport serving St. John's, the capital of Newfoundland and Labrador, Canada. It handles the majority of passenger and cargo traffic for the province, connecting the island to major Canadian cities and select international destinations. The airport is operated by the St. John's International Airport Authority and serves as a critical transportation hub for the region, supporting both commercial aviation and offshore oil-industry-related air traffic. It has undergone significant infrastructure upgrades in recent decades to modernize facilities and expand capacity. Due to its position on Canada's easternmost point, YYT has historically served as a technical stop for transatlantic flights requiring fuel, though this role has diminished with modern long-range aircraft.
