Construction of today's Airport began in 1950 near the suburb of Barca. An airshow took place in 1951 to mark its opening. By 1954 the runway extended to 2000m. In the same year construction began on the first part of the new passenger terminal, hanger and new control tower. In 1955 direct flights began between Kosice 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 1100m, the power supply rebuilt and a lighting system installed to meet CAT II ICAO specifications.

In the 1980s the airport's managment was forced by increasing traffic to extend its premises. During 1992-93 the runway, aprons and passenger terminal were improved, as werethe lighting, power supply, monitoring and control systems. The runway was asphalted and its loading increased. This significant improvement was remarked on by foreing crews attending the SIAD 93 airshow in Kosice. The terminal was enlarged again in 1995 and 1999.
