Ljubljana Airport

Ljubljana is an airport where recent European aviation history shows up as if under a magnifying glass. Until 2019, Brnik was home to Adria Airways, a Star Alliance airline with CRJ regional jets and connecting traffic to the Western Balkans. Then came the insolvency, and the airport – owned since 2014 by the Frankfurt group Fraport – had to reinvent itself. Today almost only foreign airlines land here, and that is exactly what makes the place interesting for spotters: little traffic, but lots of different liveries, and the peaks of the Kamnik–Savinja Alps behind them.

From Polje to Brnik

Ljubljana’s first civil airport was at Polje on the eastern edge of the city and opened in 1933. For the growing air traffic of the postwar period the site was too small, so a new location was sought – and found on the plain near Brnik in Upper Carniola, a good twenty kilometers northwest of the city. The new airport opened in December 1963, and scheduled service began in January 1964. Because the name of the village is much shorter than the official designation, many Slovenes still simply say “Brnik” when they mean the airport.

Two years after it opened, the young airport suffered its worst accident. On the night of September 1, 1966, a Bristol Britannia of the British charter company Britannia Airways flew into trees on approach to Brnik; 98 of the 117 people on board were killed. The investigation named an incorrectly set altimeter as the cause – the aircraft flew a much lower approach than the crew assumed. It remains the deadliest aviation accident in Slovenia to this day.

In Yugoslav times, Ljubljana was above all home to the airline that would shape the airport for decades: Adria. The state-owned JAT also served the airport. In 1991, after Slovenia’s declaration of independence, Brnik moved to the center of the Ten-Day War: on the first day of the war the airport was bombed, and four Adria Airways aircraft were heavily damaged. Not far from the grounds, two foreign journalists were killed when their car was hit.

Adria Airways: rise and end of the home airline

Anyone who wants to understand Ljubljana Airport has to start with Adria Airways. The airline was founded in March 1961 as Adria Aviopromet and started in December of the same year with two used Douglas DC-6Bs that it had taken over from KLM. At the end of the 1960s it teamed up with the Belgrade trading group InterExport and flew as Inex-Adria – the name under which many older spotters still know it. In 1969 the DC-9 brought the first jet, followed later by aircraft of the MD-80 family, Dash 7 turboprops and finally the Airbus A320. From 1986 the company was called Adria Airways.

After independence, Adria became Slovenia’s national airline. Its network linked Ljubljana with the big hubs in Central and Western Europe, and because it also served destinations in Bosnia, Kosovo, North Macedonia and Albania, many travelers from the Western Balkans connected at Brnik. On November 18, 2004, Adria joined Star Alliance. In its last years, the fleet consisted mainly of Airbus A319s, CRJ700 and CRJ900 regional jets and Saab 2000s.

In 2016, the Slovenian state sold 96 percent of the shares to the Luxembourg restructuring fund 4K Invest. The financial situation remained tense, flight cancellations piled up in the summer of 2019, and lessors took aircraft back. On September 30, 2019, Adria Airways ceased operations and filed for insolvency. For the airport this was a hard blow: Adria was by far the most important customer, and a large part of the route network disappeared at once. With the airline, the connecting traffic to the Western Balkans also vanished; according to Fraport Slovenija it had made up about 200,000 passengers a year – travelers who never set foot in Slovenia. How Adria fits into the series of major airline collapses is shown in the article on the big airline bankruptcies in Europe.

Fraport takes over: privatization and new terminal

Even before the end of Adria, the airport’s ownership structure had changed fundamentally. In 2014, Slovenia launched the privatization of the operating company Aerodrom Ljubljana. The winning bidder was Fraport AG, the operator of Frankfurt Airport: it first bought 75.5 percent for about €177.1 million and took over the remaining shares by March 2015. Since then the airport has belonged entirely to the Frankfurt group; the operating company now trades as Fraport Slovenija. In Europe, Fraport also operates the Bulgarian airports of Varna and Burgas as well as 14 Greek regional airports, including Thessaloniki.

The biggest construction project of the Fraport era is the terminal extension. As early as 2007, the old terminal had been expanded by an upper floor and four jet bridges for Slovenia’s accession to Schengen; a second construction phase with a separate Terminal 2 failed in 2013. Fraport took the topic up again: in July 2019, construction began on an annex of about 10,000 square meters west of the existing building, it was presented in June 2021 and put into operation in July – just in time for Slovenia’s EU Council presidency. The investment was about €21 million. Capacity in the departure area rose from roughly 500 to about 1,250 passengers per hour, along with a new baggage sorting system, two long baggage belts, a lounge and another jet bridge.

In the long term, the airport’s master plan also provides for a cargo terminal, a larger apron and a commercial and logistics area with a hotel. How quickly these parts are built depends on traffic – more on that below.

One runway in front of the Alps

The layout is simple: the airport has a single paved runway, 12/30, 3,300 meters long and 60 meters wide. For approaches to runway 30 there is a Category IIIb instrument landing system that still allows landings in very poor visibility. At Brnik that is no luxury: the plain between the Sava and the Alps is prone to fog, especially in autumn and winter. How such a precision approach works is explained in the article on the ILS approach.

As everywhere, the wind decides which direction is active – aircraft take off and land into it whenever possible. For you that means: before your visit, check whether aircraft are landing on runway 12 or 30, and then pick the matching runway end. The basics are in the article Understanding runway direction in use at airports; with a weather map as described in Windy and other weather maps for spotters you can see wind and clouds the day before.

Who lands at Brnik today

Since the end of Adria, the picture on the apron has changed completely. Today Ljubljana is a destination airport for foreign airlines, connected mainly to other carriers’ hubs. After the insolvency, the operator worked to secure links to the big hubs and to bring new airlines to Brnik. You can see the result in today’s schedule (as of October 2026):

• Hub feeders: Turkish Airlines to Istanbul – the busiest route in 2024 with about 192,000 passengers –, Lufthansa to Frankfurt and seasonally Munich, Swiss to Zurich, KLM to Amsterdam, Air France to Paris, Brussels Airlines to Brussels and LOT to Warsaw.
• Balkans and Southeastern Europe: Air Serbia links Ljubljana with Belgrade, Aegean with Athens, Wizz Air with Skopje and Podgorica.
• Low-cost and city traffic: easyJet to London Gatwick and other UK destinations, plus Pegasus to Istanbul Sabiha Gökçen, Vueling to Barcelona and seasonally Iberia to Madrid.
• Long-haul connection via the Gulf: flydubai flies to Dubai – the most important year-round link outside Europe.
• Seasonal: among others British Airways to London Heathrow, Norwegian to Copenhagen, Israir to Tel Aviv, Finnair to Helsinki and Luxair to Luxembourg.

In summer, numerous charter flights are added. According to Fraport Slovenija, Hurghada, Antalya, Tunisia, Sharm El-Sheikh and Rhodes were the most popular charter destinations in 2025. At the 2024 summer peak, the airport counted 22 airlines with 25 scheduled destinations and 57 leisure destinations in charter traffic. Because the schedule at Ljubljana changes especially often, the rule is: check the current arrivals board before your visit.

Which type operates a given rotation is often decided by the airline at short notice – on the feeder routes, regional jets and smaller Airbus models alternate depending on season and load. The article Telling regional jets apart helps you identify them.

Traffic: the long road back

The numbers tell the story of recent years quite clearly. In 2004, Ljubljana counted one million passengers in a year for the first time, and in 2018 the airport reached its highest level to date at about 1.8 million. In 2019 it was already slightly below that, then the end of Adria and the pandemic followed in quick succession: in 2020 the number fell below 300,000 passengers. Since then it has been climbing step by step.

What is remarkable is that growth now comes from a different source than before. Before 2019, a noticeable share of traffic was connecting passengers between Western Europe and the Balkans; today it is mostly people traveling to and from Slovenia. According to Fraport Slovenija, individual routes such as Istanbul, Zurich, Brussels, Warsaw, Belgrade and Skopje were already above their 2019 level in 2024.

For you this means: operations come in waves. In the morning the feeders depart for the hubs, at midday and in the evening they come back, and on summer weekends the leisure flights mix in. In between there are quiet phases. Cargo, at about 12,000 tonnes a year, plays a minor role but regularly delivers its own subjects – such as the DHL connection to Leipzig/Halle. How to reliably identify freighters is covered in the article Recognizing cargo aircraft.

Spotting at Ljubljana

A designated spotter area with fixed photo positions, like at some Austrian airports, is not officially documented for Ljubljana. The grounds do lie in open countryside, though, and roads and farm tracks around the airfield let you watch approaches and departures. Which spots are accessible at any given time changes with construction work and closures – ask locally and follow signs and fences. What to keep in mind when spotting abroad is summed up in Spotting abroad.

Brnik’s big trump card is the backdrop. North of the airport the Kamnik–Savinja Alps rise steeply, and to the west the Julian Alps are visible in clear weather. A departing jet in front of snow-capped peaks is the shot many spotters come for. For that you need clear air – the chances are best on days after a change in the weather with a north wind or during foehn conditions, while on inversion days in autumn and winter the basin often lies under a blanket of fog.

If you have to shoot through a fence, the tips in Shooting through the fence will help. And because Ljubljana, with its waves of traffic, is typical of a small airport, it is also worth a look at Spotting at small regional airports.

Ljubljana compared

In the region, Ljubljana is one of several small capital and regional airports that share their customers. Zagreb Airport still has a Star Alliance home airline in Croatia Airlines – exactly what Ljubljana has lacked since 2019. Belgrade Airport, as the hub of Air Serbia, is the winner of the upheavals in the former Yugoslavia. Across the border lie Klagenfurt Airport, which is linked to Ljubljana by intercity bus, and Graz Airport, which, like Brnik, mainly sees feeders to big hubs.

If you want more traffic, head to Venice Airport or to Vienna: Vienna Airport with its spotters’ hill (Spotterhügel) plays in a different league. And if you want to experience the link to Fraport itself, take a look at the parent group at Frankfurt Airport. Which alliance liveries you may come across at Brnik is shown in the article on Star Alliance, oneworld and SkyTeam liveries.

Conclusion

In just a few years, Ljubljana Airport has gone through more upheaval than many larger airports in decades. The hub of a Yugoslav and later Slovenian airline became a Fraport airport that had to start almost from zero after the end of Adria Airways in 2019. Today a colorful mix of foreign airlines carries it, and passenger numbers are approaching their pre-upheaval level again.

For spotters, Brnik is not a place for mass but for variety and scenery. Many different airlines, manageable operations on one runway and the Alps in the background make for a relaxed spotting day – provided you plan schedule, wind and visibility in advance.
