Civil aviation thumb|Oslo Airport, Gardermoen, Norway's main airport. Aviation has become an important passenger transport mode since the 1960s. Aircraft is the commonly used mode of transport on longer distances, and the routes between Oslo and Bergen, Trondheim and Stavanger are all among the largest in Europe. On long distances, such as Oslo-Bodø and longer, air travel is by far the leading travel method.
