Kastoria National Airport “Aristotelis” (IATA: KSO, ICAO: LGKA) is a public airport in Argos Orestiko in the regional unit of Kastoria, Macedonia, Greece.
The airport has operated for civil traffic since March 1971. It lies just 500 m from Argos Orestiko and about 12 km from Kastoria city. Initially it handled domestic flights, but over time both the runway and terminal facilities were improved to support more aircraft.
In the late 1980s, a new terminal building of about 1,000 m² was put into service. In September 2002, a new runway measuring 2,820 m × 45 m was inaugurated, bringing the airport up to international standards and enabling it to handle a wide variety of aircraft.
Recent developments include plans for a modernization of the airport, with regional authorities working to complete long-delayed studies and improve infrastructure. In June 2025, a new air traffic control tower project was agreed upon, which would bring the airport up to more modern operational standards.
According to official sources, the sole runway (12/30) has a length of 2,698 m (8,846 ft) and an asphalt surface. The field elevation is 660 m (2,167 ft) above sea level.
The terminal is relatively small, with a capacity to serve about 150 passengers per hour, and offers basic passenger services. There are two parking positions suitable for Boeing 737-sized aircraft, plus additional space for smaller aircraft.
Kastoria Airport “Aristotelis” currently accommodates small propeller aircraft, small jets, medium jets, long-range jets, regional airliners, and large airliners, thanks to its runway length and infrastructure.
