Sochi International Airport (AER/URSS) serves the Black Sea resort city of Sochi in Krasnodar Krai, southern Russia. It is one of the busiest airports in Russia, handling millions of passengers annually, particularly during summer tourist season and winter ski seasons at nearby Krasnaya Polyana. The airport underwent a massive modernization and expansion in preparation for the 2014 Winter Olympic Games hosted in Sochi. New terminals, runways, and infrastructure were built or significantly upgraded to handle the surge in international and domestic traffic during the Games. Following the 2022 invasion of Ukraine and subsequent international sanctions, many international carriers suspended service to Russia, significantly reducing Sochi's international traffic. The airport now operates primarily on domestic Russian routes.
