At the water flood period, the aerodrome was closed. Communication between aerodrome and city was by phone, ferry (there was no bridge over Ishim River), by foot path. In the first few years the air traffic was ad-hoc by character, the timetables used to be as follows "aircraft departure on Monday morning" or "on Wednesday at sunrise". Transportation of passengers, mail and cargo were carried out by aircraft: Kalinin K-4, Kalinin K-5, Polikarpov R-5, Petlyakov Pe-2. The regular flights were established in 1934, with the following routes: 1. Alma-Ata – Karaganda – Akmolinsk – Atbasar – Kostanay – Sverdlovsk. Karaganda – Petropavlovsk – Korgalzhyn – Akmolinsk.
