Wizz Air has raised concerns that recent modifications to Serbian air transport regulations could lead to its withdrawal from Belgrade. The airline alleges the changes create an unfavorable operating environment. Specifically, Wizz Air hasn’t detailed which aspects of the regulation are problematic, but suggests they jeopardize its continued service to the Serbian capital. The European Commission is now reviewing the Serbian regulation following the complaint. This scrutiny from Brussels centers on potential breaches of the Air Transport Common Aviation Area Agreement between Serbia and the European Union. The outcome of the Commission’s assessment could impact air travel options and competition within Serbia. Further details regarding the specific regulatory changes and the Commission’s findings are pending.
