Lithuania, a small European country, has three main airports that connect it to the world: Vilnius Airport (VNO), Kaunas Airport (KUN), and Palanga Airport (PLQ). There is a fourth airport, namely Šiauliai International Airport (SQQ), yet it has no scheduled commercial flights and houses the NATO Baltic Air Policing Mission, where allies rotate in their fighter squadrons to oversee the space over the three Baltic countries.
