The study is aimed at exploring the possibility of building a new airport in Irkutsk as part of a major transport hub on the territory equidistant from the cities of Irkutsk, Angarsk and Shelekhov, close to the East Siberian Railway, R255 Siberia Federal Highway and the bypass road of Irkutsk. This problem requires evaluating the advantages of locating a new airport on the proposed site compared to the location of the existing airport within the city. The analytical and theoretical studies of the transport hub and types of air terminals proved the formation of the airport as part of a transport hub with a railway station and a bus station to be the most appropriate solution for the development of the city. A comparative analysis of time necessary to get to the new air terminal and to the old one showed that passengers would save time if the airport is placed the outside the city due to its easy access for residents of three cities. The conducted analysis of current trends in the development of the transport interchange hub formed the basis for recommendations on the choice of a hub type appropriate for the conditions of the city. The proposed hub will increase passenger traffic, areas for servicing passengers and aircraft, and the length of runways. Placing the airport as part of a transport hub on a free territory between three large cities and modernization will ensure a high level of quality of flights and passenger service, increase the quality of life of citizens, and significantly improve the ecology of the city.
