Aerotarg
Poznań Airline Society Aerotarg (also spellt Aero-Targ) was the first Polish airline. It was founded in Poznań on 21 May 1921 mainly in order to serve participants and visitors of the first Poznań International Fair. Aerotarg operated the first regular air connection in Poland - the Poznań- Warsaw route, as well as the international connection between Poznań and the Free City of Danzig (Gdańsk).
It is considered to be a precursor of the Polish flag carrier LOT Polish Airlines along with other private-owned companies which were merged into the latter in January 1929.
