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. The expansion in traffic began in 2015 when low-cost airline Wizz Air launched flights to Basel and Malmö. Shortly after, Ryanair followed the suit by announcing flights to Berlin. In 2016, both Wizzair and Ryanair announced more flights from Niš, respectively Wizzair to Dortmund, Eindhoven, Memmingen and Ryanair to Weeze, Bergamo and Bratislava. Shortly after the launch of these flights Niš experienced triple-digit growth in passenger traffic, exceeding the previous record figure. On 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, Swiss got direct competition when Germania Flug announced flights to Zurich, starting June 2017 operated by the Airbus 319. 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. Furthermore, the Serbia and Montenegro Air Traffic Services Agency (SMATSA) plans to start construction of a new control tower next year and will invest a million euros in an instrument landing system (ILS), which provides guidance to aircraft approaching and landing on a runway during low ceilings or reduced visibility due to fog, rain or snow. In January 2018, the Government of Serbia granted a 25-year concession of the Serbian largest Belgrade Nikola Tesla Airport to the French airport operator Vinci Airports for a sum of 501 million euros.
