Codeshare and interline agreements between Air France-KLM and SAS are to go live from September 1.
The change will come when the Scandinavian airline officially joins the SkyTeam alliance, switching from the rival Star Alliance as part of a rescue deal involving Air France-KLM.
SAS plans to exit the Star Alliance on August 31 as part of a restructuring deal designed to bring the carrier out of US Chapter 11 bankruptcy protection.
