Trondheim Airport, Værnes — Trondheim, Norway

TRD sits at Vaernes, in Stjordal, roughly thirty kilometers east of Trondheim, and functions as the main air gateway to central Norway's Trondelag region. The airport shares its site with a Royal Norwegian Air Force base, a dual civilian-military arrangement typical of several Norwegian airports built up during and after the Cold War. Trondheim itself served as Norway's capital during the Viking Age and remains home to Nidaros Cathedral, the country's largest medieval building and a traditional site of royal coronations. Today the city functions as a center for technology and research, anchored by the Norwegian University of Science and Technology, giving TRD a steady stream of business travel alongside tourism and domestic connections. Scandinavian Airlines, Norwegian, and Wideroe all operate routes from here, linking Trondheim to Oslo, Bergen, and smaller airports across the country, plus a modest set of seasonal international connections.
