Barnaul Gherman Titov International Airport — Barnaul, Russia

Barnaul Gherman Titov International Airport serves Barnaul, the capital of Russia's Altai Krai region in southern Siberia. The airport is named for Gherman Titov, the Soviet cosmonaut who became the second human to orbit Earth and the first to spend a full day in space, aboard Vostok 2 in 1961; Titov was born in a village in the Altai region that the airport now honors. Sitting at 837 feet above sea level, BAX operates a single runway serving both domestic Russian routes and occasional international connections. Novosibirsk's Tolmachevo Airport, western Siberia's major hub, lies about 194 kilometers away, while Gorno-Altaysk Airport sits roughly 219 kilometers to the southeast and Novokuznetsk's Spichenkovo Airport is about 226 kilometers out. BAX serves as the primary air gateway for Altai Krai, a region better known internationally for the Altai Mountains further south than for Barnaul itself, which functions as a significant industrial and administrative center in its own right.
