RUSAL's Bratsk smelter — the world's largest, turning out more than a million tonnes of aluminium a year, roughly 4 % of global output — defines this industrial city in northern Irkutsk Oblast, alongside a major pulp-and-timber complex on the Bratsk Reservoir. Bratsk Airport (IATA: BTK, ICAO: UIBB) lies about 8 km north of the city and ranks second in the region after Irkutsk, handling over 100,000 passengers a year under operator AeroBratsk. Russian carriers such as Angara, S7 Airlines and Yakutia link it to Siberian and Far Eastern points. On the freight side, BTK holds international-border status and acts as a staging base for cargo flights toward Kamchatka, though the region's heavy exports — aluminium and timber — move by rail on the Trans-Siberian and Baikal-Amur Mainline. For large-scale international air freight, Irkutsk (IATA: IKT), some 500 km southeast, is the nearest bigger gateway.
