Yuzhno-Sakhalinsk International Airport — Yuzhno-Sakhalinsk, Russia

Yuzhno-Sakhalinsk International Airport, known by the code UUS, is the principal air gateway to Sakhalin Island in Russia's Far East, facing Japan's Hokkaido across the La Perouse Strait. Also called Khomutovo Airport after the nearby settlement, it connects the regional capital to Moscow, Vladivostok, Khabarovsk, and other major Russian cities across the country's vast longitudinal expanse. Sakhalin's economy leans heavily on offshore oil and gas extraction, and the airport has long handled charter and business traffic tied to those energy projects alongside routine passenger service. A modern terminal building replacing the aging Soviet-era structure opened in the early 2020s, adding capacity for a region where winter weather and heavy snowfall regularly test operations. Fishing, forestry, and a growing wave of domestic tourism to the island's forested mountains round out the traffic mix passing through UUS.
