Low cost carrier Ryanair has been allocated slots to commence flights between Dublin and Niš during the 2024 summer season, a report by Airport Coordination Limited, a slot coordination company, shows. The airline has secured 210 aircraft movements on the route, meaning 105 flights in each direction during the upcoming summer season, which begins on March 31, 2024 and lasts until late October. The airline has allocated 39.690 seats on the route (both directions included). It is still possible for Ryanair to amend plans and use the allocated Niš slots for another destination, however, the carrier has filed to use the flight times at Dublin Airport for services to the southeast Serbian city. In 2020, Wizz Air filed for slots to operate between London Gatwick and Niš over the winter but ultimately opted to use the slots for a different route.

There are currently no flights between Serbia and Ireland. Dublin is now one of Belgrade’s busiest unserved destinations in Europe based on indirect traffic flow, after the airport added over forty cities to its network since the start of the pandemic. Despite Ireland being part of the European Union, Serbian passport holders require a visa to enter the country if they are not in possession of a valid UK visa, due to arrangements between the two island nations. However, visas can be obtained through the Irish consulate in Belgrade with significantly greater ease and less cost than that of its British counterpart.

The Serbian diaspora in Ireland is estimated to be fairly small, with some 5.000 believed to be residing in the country. Niš Airport handled a record 419.013 passengers during the January - November period, representing an increase of 17.6% on last year. During the 2023 summer season, Ryanair boasted the largest number of flights from Niš since commencing operations to the city in 2016, with a total of 301 departures, just ahead of its previous best in 2018 and up 25% from 2019 when it had 240 flights. During the 2023 summer season, the airline put 55.589 seats on sale from the southeast Serbian city, up from 45.360 in 2019.
