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 and Johan Nilsson. Its first flight was on 2 June 1924 between Stockholm, Sweden and Helsinki, Finland. Needing more funds, it became government-owned in 1935. ABA was merged with Swedish Intercontinental Airlines (SILA) in 1948 and airline operations would ultimately be merged into the international SAS Group in 1950.
