Atlant-Soyuz Airlines was a Russian airline that operated both cargo and passenger charter flights. Based in Moscow, the carrier served destinations across Russia, the CIS, and international markets, particularly focusing on freight operations alongside leisure and ad-hoc charter services. The airline operated a mixed fleet of Soviet-era and Western-built aircraft, reflecting the transitional period of Russian aviation in the post-Soviet era. Atlant-Soyuz held IATA code 3G and ICAO code AYZ, with its radio callsign designated as ATLANT-SOYUZ. The airline ceased operations in the early 2010s amid financial difficulties that affected numerous smaller Russian carriers during that period. It was never a member of any major global airline alliance.
