Foreign carriers plan to boost their operations to Belgrade this summer by adding flights and increasing capacity, ahead of VINCI's takeover of Nikola Tesla Airport. easyJet, Iran Air, and Qeshm Air will launch new routes to the Serbian capital in the coming months, while a number of carriers will increase their presence by adding frequencies on existing services, including Air Cairo, Belavia, LOT Polish Airlines, Flydubai, Vueling, Transavia, Norwegian Air Shuttle, Swiss International Air Lines, Wizz Air and TAROM. Others, such as Qatar Airways and Aegean will increase their capacity. Overall, foreign carriers are expected to boost their passenger share in Belgrade, which stood at 50% in 2017.

Low cost airline easyJet will operate services to Belgrade from three different cities this year - Geneva, Berlin and Basel - the latter two being introduced over the summer. Despite uncertainly over its Geneva route, the airline has now scheduled and put on sale flights from the Swiss city, which were initially scheduled to run only until the end of March. On the other hand, following several delays, Iran Air has entered its new service from Tehran to Belgrade into Global Distribution Systems with the launch date set for March 3, although slight changes to the initial schedule have been made. Overall, the airline will maintain two flights per week with ticket sales to commence soon.

Belarus' national carrier Belavia, which runs two weekly flights between Minsk and Belgrade via Budapest, will commence nonstop operations between the Belorussian and Serbian capitals by adding a third weekly service, the remaining two will continue to be maintained via Budapest. The airline holds fifth freedom rights on the sector between Belgrade and the Hungarian capital, allowing it to sell tickets for the city pair. Furthermore, Transavia will double its operations to six per week during the height of the summer season, while Swiss International Air Lines will introduce an extra two weekly flights to Belgrade, for a total of sixteen. LOT will increase its frequencies from Warsaw from nine to eleven weekly services starting July 6, while Spanish carrier Vueling will bring forward its flights from Barcelona to the Serbian capital and maintain operations during the entire 2018 summer season. Meanwhile, Air Cairo will boost its frequencies between Cairo and Belgrade from three to five per week.

Other notable additions to Belgrade Airport's summer line-up will include the deployment of Qatar Airways' 182-seat Airbus A321 aircraft on its daily flights from Doha, while Flydubai will run daily services with its new Boeing 737 MAX aircraft, featuring its new business and economy class product. The airline is also mulling potential additional frequencies over the height of the summer season. The future operator of Belgrade Airport is expected to sign the concession agreement with the government later next month. The Serbian government has said that the planned revenue from VINCI's concession and investment over the next 25 years will amount to 1.5 billion euros, while the annual concession fee will range between 4.3 million and sixteen million euros.
