Sørfly operated a fleet of three Auster Autocrats, a Republic Seabee and a Miles Gemini.
For most of its history the airline provided aerial photography, target tug, air ambulance, passenger and cargo charter and sightseeing services as the baseline for its revenue.
From 1948 to 1951 it also operated a scheduled service on behalf of Norwegian Air Lines from Kristiansand to Aalborg and Gothenburg, and to Stavanger.
Sørfly was founded during early 1946 by four pilots and mechanics: Einar Jaatun, Ragnar Moi, Finn Erikstad and Jonny Thorsen.
Other important contracts were transporting cement to Skjerka and target tug for the Royal Norwegian Air Force.
This allowed the airline to start charter flights along the coast and access to mountain cabins during the summer.
By the turn of the decade several of the founders had quit and the airline was gradually shut down, with operations suspended in 1962.
