Sheremetyevo International Airport — Moscow, Russia

As Aeroflot's primary hub and the airport most associated with Moscow's international air links since the Soviet era, SVO has handled decades of diplomatic, business, and tourist traffic north of the Russian capital. Its terminals expanded significantly ahead of the 1980 Moscow Olympics and again in the years that followed, reflecting the airport's role as the country's showcase gateway to the wider world. Sheremetyevo gained unusual global attention in 2013 when American intelligence contractor Edward Snowden spent more than a month in its transit zone before Russia granted him asylum, a story that briefly made the airport itself a fixture of international news coverage. A high-speed rail connection, the Aeroexpress, links the airport to central Moscow in well under an hour. Multiple interconnected terminals, expanded through several construction phases, now handle a substantial share of Russia's international passenger volume alongside significant domestic traffic across the country's vast network.
