Šiauliai International Airport (IATA: SQQ, ICAO: EYSA) is located near Šiauliai, the fourth-largest city in Lithuania. The airport serves both civil aviation and military purposes, sharing its facilities with the Lithuanian Air Force base, making it a dual-use aerodrome of strategic importance. Commercial passenger traffic at Šiauliai is limited compared to Vilnius or Kaunas airports, with the airport handling primarily charter, cargo, and general aviation flights. Its long runways, originally built during the Soviet era, make it capable of accommodating large aircraft and contribute to its continued military relevance within NATO operations in the Baltic region. The airport has historically been used for cargo operations and occasional low-cost charter services, though scheduled commercial traffic has remained sparse. Its infrastructure supports NATO air policing missions conducted from Lithuanian territory.
