✈ Banja Luka Airport Summer Timetable 2025

Banja Luka Airport is set to experience an increase in both flights and seat capacity, as Ryanair expands its services to include more flights from Gothenburg and Stockholm. Meanwhile, Wizz Air will ramp up its operations from Basel, offering flights six times a week (daily except Saturdays) for most of the summer season.

Air Serbia, which had initially planned to increase its flights from Belgrade to three weekly services, has now canceled this plan. Instead of offering daily flights Air Serbia will reduce its services from three to just two weekly flights. Given Air Serbia’s lack of interest in developing the Belgrade-Banja Luka route, the airport may want to consider offering subsidies to a European legacy carrier to establish at least one direct connection to a major hub. This would provide convenient one-stop access to wide range of global destinations.

Austrian Airlines, with its five weekly flights to Vienna, or Turkish Airlines, with three to five weekly flights to Istanbul, would be ideal candidates to serve such a route.

Additionally, the following airlines will not be returning to Banja Luka this summer:

• Air Cairo, Hurghada 
• Nouvelair, Monastir
• Tailwind, Antalya

✈Sarajevo Winter 2023-24

The 2023/24 winter timetable enters into force on Sunday, October 29th, 2023. until March 30th of 2024. During this time period the passengers will be able to fly from Sarajevo Airport with 14 airlines to 14 destinations in 10 countries across Europe and the Gulf region.

New destination this winter season is Skopje, which will be served with 3 weekly flights by the Greek airline Olympic Air on behalf of Aegean Airlines. The flights are scheduled to begin on October 02, 2023. and will operate on Mondays, Wednesdays and Fridays with ATR-72 aircraft offering 72 seats.

After the pause of 5 months,  Wizz Air is returning with two weekly flights from London Luton to Sarajevo beginning September 25, 2023.

From November of this year Wizz Air is discontinuing Abu Dhabi-Sarajevo flights due to issues with engines on its Airbus 321neo aircraft and the grounding of 10% of its whole fleet. This route is very popular with tourists from both UAE and Bosnia, visiting each other countries. The flights were initially introduced with two weekly flights in October of 2021, but due to the high demand, the flights were increased to five per week and then to daily from March of this year.Before Wizz Air started flights from UAE to Sarajevo, Air Arabia operated flights from both Sharjah and Abu Dhabi. During the summer months Air Arabia operated two daily flights from Sharjah and 3 weekly flights from Abu Dhabi. With Wizz Air suspending Abu Dhabi-Sarajevo flights is very likely to see Air Arabia back in Sarajevo from April of next year. Earlier this month United Arab Emirates abolished entry visas for citizens of Bosnia and Herzegovina, which will create additional demand for air travel between two countries.

Air Serbia is increasing flights from Belgrade to Sarajevo to 7 flights per week (two additional flights per week when compared to the winter of last year).

Austrian Airlines is increasing flights from Vienna to Sarajevo to 13 flights per week (one additional flight per week when compared to the winter of last year).

Turkish Airlines is increasing flights from Istanbul-IST to Sarajevo to 14 flights per week (five additional flights per week when compared to the winter of last year).
