Air Serbia will utilise an Etihad Airways-branded Airbus A330 aircraft on flights between Belgrade and New York on a temporary basis betweeen January 12 and February 14, 2019, while its own jet of the same type undergoes scheduled maintenance checks at Etihad Airways Engineering in Abu Dhabi ahead of the busy summer season. In a statement, Air Serbia said, "Passengers can look forward to experiencing Air Serbia’s traditionally warm service on these flights, provided by Serbian-speaking Etihad and Air Serbia cabin crew, while also enjoying an extensive range of films, music and TV shows on Etihad's in-flight entertainment systems". In its flight permit application with the US Department of Transportation in 2016, Air Serbia foresaw and applied for the use of Etihad equipment on its US-bound flights. In its application at the time, it noted, "Air Serbia and Etihad have agreed to a contingent wet lease pursuant to which Etihad may wet lease aircraft to Air Serbia in the event of maintenance problems or other issues that might take its aircraft out service for any length of time".
