Oskemen International Airport — Ust-Kamenogorsk (Oskemen), Kazakhstan

Oskemen International Airport, known by its IATA code UKK, serves the city of Oskemen, called Ust-Kamenogorsk in Russian, the administrative center of Kazakhstan's East Kazakhstan Region near the borders of Russia and China. The surrounding area is one of the country's most important centers of non-ferrous metallurgy, home to major titanium, zinc, and rare-metal processing plants that grew out of Soviet-era industrial planning. Positioned close to the Irtysh River and the foothills of the Altai Mountains, the city and its airport also serve as a starting point for travelers heading into scenic mountain terrain near the borders with Russia, China, and Mongolia. Air Astana and other Kazakhstani carriers connect UKK to Almaty and the capital Astana, supporting both business travel tied to the metals industry and a modest but growing tourism trade in the Altai foothills.
