Airtaco (founded in August 1950 as Aero Scandia) can be considered as Linjeflyg's predecessor and was merged into the new airline, including its entire fleet.

[1] When Linjeflyg was founded, Airtaco's four Lockheed Model 18 Lodestars and four Douglas DC-3s were integrated into the new fleet.

On 10 September 1990 Scandinavian Airlines System (SAS) sold their 50% in Linjeflyg to Bilspedition for 475 million Swedish crowns (SEK).

In February 1992 Linjeflyg became too big a threat for SAS, because it planned a strategic alliance with Braathens and Maersk Air.

Such an alliance would have been too competitive for SAS on the intra-Scandinavian capital routes and on domestic flights.
