The airports in Zagreb, Belgrade and Pristina will be the fastest-growing in the former Yugoslavia during the upcoming third quarter (July, August and September). The trio will add the most scheduled capacity compared to the same period the previous year.
Zagreb Airport is set to lead in capacity growth, adding 252,137 extra seats. The increase is largely driven by Croatia Airlines, which will launch five new routes in early July and boost capacity with the arrival of Airbus A220-300 aircraft, following the retirement of two Dash 8 turboprops earlier this year. Ryanair is also contributing to the growth with additional frequencies, while Turkish Airlines plans to operate up to four daily flights to the Croatian capital for the first time.
Belgrade Airport will see an increase of 244,445 additional seats this summer, driven primarily by Wizz Air and Air Serbia. Wizz Air is adding 120,938 seats in the third quarter, supported by the introduction of two new routes, frequency increases, the return of a fourth based aircraft, and a fleet shift from A320s to larger A321neos. Meanwhile, Air Serbia, which is launching five new routes in the second quarter, will contribute an extra 26,280 seats during the upcoming three-month period.
In Pristina, the strong growth can be attributed to GP Aviation, along with Wizz Air, Turkish Airlines and Pegasus. All airports across the former Yugoslavia, with the exception of Osijek, are expected to see an increase in scheduled seat capacity during the third quarter. Osijek Airport will register a minor 1.4% decline, primarily as a result of four fewer operations by Ryanair during the three-month period.
The table above is of an informative nature and is correct as of June 21. Airlines regularly adjust capacity by changing aircraft types, modifying frequencies, or adding and suspending routes, which may lead to changes in the figures as the third quarter of 2025 progresses, EX Yu Aviation news writes.
