Stockholm-Arlanda Airport

Stockholm-Arlanda Airport is the largest and busiest airport in Sweden, serving as the primary international hub for the Stockholm metropolitan area and the country as a whole. Located approximately 40 kilometres north of central Stockholm in Sigtuna Municipality, Uppsala County, it handles the majority of Sweden's long-haul and intercontinental traffic. The airport is operated by Swedavia, a Swedish state-owned airport operator. It serves as the main hub for Scandinavian Airlines (SAS) and is a significant base for Norwegian Air Shuttle. Arlanda consistently handles around 25–27 million passengers per year in pre-pandemic conditions, making it one of the busiest airports in Scandinavia. Arlanda has four terminals: Terminals 2, 3, and 5 handle international and Schengen traffic, while Terminal 4 is used for domestic flights. The airport has undergone significant expansions over the decades to accommodate growing passenger demand and increasing numbers of long-haul routes.
