AB Aerotransport

  (Redirected from Aerotransport)

AB Aerotransport (ABA) was a Swedish government-owned airline which operated during the first half of the 20th Century and was merged into what would become the SAS Group. ABA was established on 27 March 1924 under the name Aktiebolaget Aerotransport by Carl and Adrian Florman together with Ernst Linder, John Björk och Johan Nilsson.[1] Its first flight was on 2 June 1924 between Stockholm, Sweden and Helsinki, Finland.[2][3] Needing more funds, it became government-owned in 1935.[1] ABA was merged with Swedish Intercontinental Airlines (SILA) in 1948 and airline operations would ultimately be merged into the international SAS Group in 1950.

In 1925 the company started a route between Stockholm and Berlin in co-operation with Lufthansa and a mail route connecting Stockholm with Malmö, Sweden, Amsterdam, Netherlands and London, England. Passenger service to Moscow, USSR was begun in the late 1930s.

During World War II ABA tried to maintain their network, but in 1941 the route to Moscow was closed, and the route to Berlin ceased in 1945. During the war ABA had a courier flight between Stockholm and Scotland. After the German occupation of Europe ABA started new routes to Paris, Oslo and Prestwick.

In June 1948, after a Swedish report, the government-owned ABA and privately owned SILA were merged on a 50-50 basis, to form a new airline named ABA. SILA had become the Swedish part of SAS in 1946, which at that time only a co-operation between DDL in Denmark and DNL in Norway. However, on October 1, 1950, representatives from the three airlines signed a consortium agreement where they appointed SAS to run the airline operations and the three national airlines only to be holding companies.


ABA was the first airline with three-engine passenger aircraft when in 1925, ABA bought three Swedish Junkers G.24 from AB Flygindustri. During the following years ABA used and bought several different aircraft (e.g. Junkers F.33, F.34, G.23, G.24). For the longer routes a Fokker F.XII was used.

In 1937 ABA became the second European operator of the Douglas DC-3 after KLM. This opened opportunities to fly "longer flights" for example to Moscow. In 1939 ABA started to mark their aircraft with Swedish Air Lines.
