Military aviation
Construction of today's airport began in 1950 near the suburb of Barca. In 1954 construction began on the first part of the new passenger terminal, hangar and new control tower. In 1955 direct flights began between Košice and Prague. The power supply was enhanced by more powerful transformers in 1962. Increasing traffic required a larger passenger terminal by the mid 1960s. The foundation of the SNP Air Force Academy in 1973 strengthened aviation in the then republic of Czechoslovakia. Between 1974 and 1977 the runway was increased by , the power supply rebuilt and a lighting system installed to meet CAT II ICAO specifications. Military aviation at the airport stopped in 2004.
