included a ban on international air travel. In these circumstances the volume of traffic reached its lowest point with the only route being to Tivat Airport during the summer period. In 1998, the traffic volume increased owing to the heavy air traffic from Pristina International Airport which was out of use because of numerous foggy days during which the traffic was successfully carried out from Niš. The airport was heavily damaged during the 1999 NATO bombing of Yugoslavia. The airport was reopened in 2003 with the financial assistance from government of Norway. Damage sustained during the bombing was repaired, including the building of a new control tower and renewal of the terminal building. In 2004, Jat Airways and Montenegro Airlines resumed flights from Niš to Zurich, Paris, and Tivat. In 2010, Wind Jet connected the airport with Forlì, Italy while Montenegro Airlines linked it with Podgorica on a daily basis. The route to Podgorica was discontinued in 2013 because of low passenger numbers. For more than two years (2014-2015) there were only charter flights to and from Niš.

Shortly after the launch of these flights Niš experienced triple-digit growth in passenger traffic, exceeding the previous record figure. In October 2016, Turkish Cargo, the airline for the transport of cargo which is a part of Turkish Airlines commenced scheduled cargo service between Niš and Istanbul. In November 2016, Swiss International Air Lines announced flights to Zurich, operated by the Airbus 320.

In December 2016, it was announced that Constantine the Great Airport airport began overhaul of its terminal by expanding check-in and boarding space, as well as building a new exterior and fixing the roof. The project is being funded jointly by the Government of Serbia and local authorities.
