Zabaikal Airlines is a small Russian regional carrier operating in the Zabaikal (Transbaikal) region of eastern Russia. The airline provides air services connecting remote communities and regional centers that are otherwise difficult to access by road or rail, particularly in the vast and sparsely populated areas of the Russian Far East. The airline operates under the IATA code Z6 and ICAO code ZTT, using the radio callsign BAIKAL. Like many small Russian regional carriers, Zabaikal Airlines focuses on domestic routes serving local transportation needs rather than competing on major trunk routes. The carrier reflects Russia's broader efforts to maintain air connectivity in remote Siberian and Far Eastern territories, where aviation often serves as a critical lifeline for isolated settlements.
