The Scandinavian Air Express saw the light at the end of the 1920’s as a joint venture between KLM (Royal Dutch Airlines) and ABA (AB Aerotransport) joined later by Aero O/Y. Their intention was to cooperate in services to France and UK, later, when Aero O/Y joined them, they extended the operations to Sweden and Finland. World War 2 put an end to that well-conceived enterprise.
