Wizz Air says new Serbian aviation rules could force it to close its Belgrade base from November 2026, escalating a regulatory dispute over foreign-carrier operating rights in Serbia. The airline says amendments adopted by the Civil Aviation Directorate in March would make its base operations untenable and conflict with the European Common Aviation Area agreement.
The changes were signed on 27 March 2026 by Acting Director Ognjen Babić and revise the authorisation regime for foreign airlines operating international services to and from Serbia. Wizz Air says the wording would affect aircraft and crews based in Belgrade, where it currently operates a four-aircraft base serving 23 destinations.
Serbian regulators reject that interpretation, saying the amendments do not restrict traffic rights and apply equally to all carriers. Wizz Air has raised the issue with the European Commission, EASA and Hungarian authorities, turning the matter into a test of Serbia’s aviation liberalisation framework and its relationship with EU rules.
