Stockholm-Arlanda Airport

Stockholm-Arlanda is Sweden's dominant gateway and the largest airport in the Nordic region by passenger volume, handling 26.3M travelers (2024) across 160 destinations on 66 airlines. ARN sits 37 km north of central Stockholm on a 20,000-acre (8,100 ha) site in Sigtuna municipality — a footprint many times larger than Arlanda's traffic volume would suggest, reflecting Swedavia's long-term masterplan to accommodate a second city-pair hub and significant cargo expansion. SAS Scandinavian operates its largest hub at ARN as the flag carrier of a multi-national alliance (Sweden, Denmark, Norway), feeding Star Alliance long-haul connections to the U.S., Asia, and southern Europe. Norwegian and BRA (Braathens Regional) run substantial secondary bases, and Ryanair, Wizz Air, and easyJet maintain low-cost operations alongside full-service carriers serving the Baltic, Nordic, and continental European markets. Four terminals are grouped into two connected buildings: Terminals 2 and 5 handle international Schengen/non-Schengen traffic, while Terminals 3 and 4 serve primarily domestic and Nordic routes. Three runways — 10,830 ft (3,301 m), 8,202 ft (2,500 m), and 8,201 ft (2,500 m) — operate under strict night-noise restrictions. The airport sits at 137 ft (42 m) elevation on the Uppsala plain and is one of Europe's leading examples of airport sustainability programming: Arlanda was the first airport in the world certified carbon-neutral, operates a geothermal aquifer thermal energy storage system for terminal climate control, and has committed to fossil-free ground operations. ARN's strategic position as the northernmost major hub in Europe gives it a distinctive role in polar-route connections between North America and North Asia, and SAS's transatlantic operation uses Stockholm as a third-gateway complement to Copenhagen and Oslo.
