Niš Constantine the Great Airport welcomed 32.261 passengers during the first half of the year which is just under the 36.258 travellers handled over the whole of 2015. The airport estimates it will surpass the 100.000 passenger mark by the end of the year. The greatest share of travellers using Niš Airport are Serbs working and living abroad, followed by tourists and businesspeople. "Among tourists, there are Serbs visiting Sweden and Switzerland, while some tour operators also organise visits from Sweden to Niš", Niš Airport spokeswoman, Ivanka Stanisavljević, says. She adds that over the past few months there has been an increase in the number of travellers from neighbouring Bulgaria and Macedonia using the airport. Both Wizz Air and Ryanair will introduce new flights to the city this summer and next winter.
