Vnukovo International Airport — Moscow, Russia

Vnukovo International Airport, designated VKO, is the oldest of Moscow's major airports, having opened southwest of the Russian capital in 1941. For decades it served as the primary airport for Soviet leadership, and it remains home to a government terminal used for state visits and official flights involving foreign dignitaries. As Sheremetyevo became the main hub for long-haul international service, Vnukovo focused increasingly on domestic routes across Russia and the former Soviet states. The airport has since modernized its runways and terminal buildings, and several Russian carriers, including UTair, have based substantial operations there. Vnukovo today shares Moscow's air traffic with Sheremetyevo and Domodedovo, forming one of three major gateways serving the capital region. Its long history and continued government role set VKO apart from Moscow's other international airports.
