Irkutsk International Airport (IKT/UIII) is the primary aviation hub for the Irkutsk Oblast in eastern Siberia, Russia. It serves both domestic routes across Russia and a selection of international destinations, particularly to cities in Asia including Beijing, Seoul, and various Chinese cities. The airport is a key transit point for travelers visiting Lake Baikal, one of the world's most famous freshwater lakes located roughly 70 kilometers from the city. It handles a significant volume of traffic given Irkutsk's role as a major regional center in eastern Siberia. The airport has undergone various infrastructure upgrades over the years to accommodate growing passenger numbers and modernize its facilities, though it remains a mid-sized regional airport by international standards.
