Cheboksary Airport — Cheboksary, Russia

Capital of the Chuvash Republic along the Volga River, Cheboksary relies on CSY for the bulk of its air links to the rest of Russia, chiefly Moscow. Built during the Soviet period, the airport has seen periodic renovation to its terminal and runway surface without expanding into a major hub, reflecting the modest population it serves. Domestic carriers operate a limited schedule, and seasonal charter flights occasionally supplement the regular routes. The airfield remains a practical alternative to the longer road or rail journey toward larger aviation centers such as Kazan or Nizhny Novgorod.
