May 1923 as the Belgian national carrier. It took over from Belgium's previous airline, SNETA (Syndicat Aeriens pour l'Etude des Transports Aeriens) which was formed in 1919 as a national airline.
SABENA AIR LINES' first paying flight was on 1 April 1924 on a flight from Rotterdam to Strasbourg stopping at Brussels. Regular flights to Amsterdam and Basle via Strasbourg were started by 1923 with further routes to London, Bremen and Copenhagen by 1924..
When SABENA was formed it was part funded by Belgians in the Congo colony who had only a year before lost their air service - an experimental passenger and cargo company (L.A.R.A.) between Kinshasha, Lisala and Stanleyville - and expected the new Belgian national airline to fill this gap. So from 1925 SABENA pioneered a route to Africa and to Belgium's interests in the Belgian Congo.
