Olyokminsk Airport — Olyokminsk, Russia

OLZ is the code for Olyokminsk Airport, serving the remote town of Olyokminsk in the Sakha Republic of Russia, deep in Siberia along the Lena River. Given the extreme isolation and harsh climate of the region, OLZ functions as a critical transportation link, since road access to Olyokminsk is limited or seasonal, particularly during winter thaw periods when ice roads become unusable. The airport primarily handles domestic flights connecting the town to Yakutsk, the regional capital, using small to medium-sized Russian-built aircraft suited to the short runways and challenging conditions typical of Siberian aviation infrastructure. OLZ remains a lifeline for residents, cargo, and medical transport in this sparsely populated part of the Russian Far East.
