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).
To do so, on 10 May 1921 the Poznań Airline Society Aerotarg was established.
Aerotarg began cooperation with a haulage company from Danzig - Danziger Luftpost which subsequently leased six Junkers F 13 aircraft to the newly created airline.
The Polish Post used the airline to send airmail and issued a special series of stamps to allow for it.
The venture turned out to be unprofitable and the 5 million marks of the seed capital were not returned to the organizers of the fair.
