Bilbao Airport

Bilbao is a city people associate with architecture – and the airport fits right in. If you look at the terminal on approach or from the fence, you see a white building lying over the apron like a bird with outspread wings. It was designed by Santiago Calatrava, who also built the Zubizuri pedestrian bridge in Bilbao. For you as a spotter, though, BIO is more than an architectural subject: a compact main runway between green hills, a colorful mix of low-cost airlines and network carriers and weather that tests every photo plan.

From military airfield at Sondika to Calatrava airport

The airport’s history begins in the 1930s. As early as 1936, the authorities approved an airfield at Sondika, which was built during the Spanish Civil War, and at first the site served military purposes. The airport began civil scheduled service on September 19, 1948 – with a connection to Madrid and a runway of just around 1,440 meters in length.

In the following decades, Bilbao grew step by step. In the mid-1960s, the runway was extended to 2,000 meters and equipped with an instrument landing system. At the end of the 1970s, today’s main runway 12/30 at 2,600 meters was added; the old runway has been the secondary runway 10/28 ever since. The big leap came around the turn of the millennium: in 1999 the new tower entered service, and in November 2000 the new terminal on the north side of the grounds in Loiu. The old facilities in Sondika on the south side thereby lost their role in passenger traffic.

Today the Spanish airport group Aena operates the airport, like almost all of the country’s big commercial airports – from Madrid-Barajas Airport to Barcelona-El Prat Airport.

La Paloma: the terminal as a photo subject

The terminal is the reason many visitors associate Bilbao with the airport at all. Calatrava designed a building whose roof spans the facade like two wings; the nickname “La Paloma” – the dove – comes exactly from that. Handling runs via jet bridges right at the building and via remote stands that passengers reach by bus.

As elegant as the building is, it has been criticized just as often. Calatrava had dispensed with a classic canopy on the arrivals side – not exactly practical in the rainy Basque Country. A glass shelter was therefore added afterward. And the terminal was designed for around 4.5 million passengers a year, a number Bilbao had nearly reached as early as 2007 and now clearly exceeds.

For spotters, the terminal is above all a backdrop. A Vueling A320 in front of La Paloma’s white wings immediately says where the picture was taken – few airports manage that. As the aircraft taxi, watch whether you can get the distinctive roofline into the frame.

One main runway, two directions

The runway system is quickly explained. Almost all scheduled traffic runs over the main runway 12/30, 2,600 meters long and 45 meters wide. The secondary runway 10/28 lies at an angle to it and is usable for a much shorter length; it serves mainly small aircraft and as an alternate runway when the main runway is closed.

According to the airport information, 30 is the preferred direction – the more capable landing system for poor visibility is also installed here. Runway 12 is used mainly with a south wind. That is decisive for your choice of spot: if you set yourself up for approaches to 30, you’re usually right, but before setting off you should check whether the weather happens to call for the opposite. How to estimate the runway direction in use in advance is explained in the article Understanding the runway direction at airports.

Wind, hills and Atlantic weather

Bilbao lies only a few kilometers from the Bay of Biscay, framed by hills and mountains. That has two consequences. First, the weather is typically Atlantic: many days with low clouds, drizzle and quick changes, especially in the winter months. Second, the wind can become treacherous in this terrain. In south wind conditions, the air descends over the Basque mountains, and the approach then gets rough. In February 2001, an Iberia A320 hit wind shear on landing, the nose gear collapsed – everyone on board survived.

For spotters, that means: windy days can deliver exciting landings in which the crews visibly have to work. What happens in the cockpit in a crosswind and why the aircraft then approach at an angle, you can read in the article on crosswind landings. And when it’s gray yet again: how to take usable pictures even under clouds is covered in the article Plane spotting in bad weather.

Who flies in Bilbao

Bilbao is not a hub but an airport with plenty of point-to-point traffic – and one clear top dog. Vueling maintains a base in Bilbao and carried just under half of all passengers in 2025. The subsidiary of the International Airlines Group flies from here to numerous Spanish and European destinations, above all Barcelona. Also represented with a base is Volotea, which mainly serves mid-sized cities in Spain, Italy and France.

On the domestic route to Madrid, Iberia and Air Europa share the traffic. Madrid was by far the busiest connection in 2025, followed by Barcelona. Iberia mainly uses A320-family types; depending on the schedule, regional jets such as the CRJ1000 can also show up via Air Nostrum as Iberia Regional.

Europe’s big network airlines send their feeders to Bilbao. Lufthansa flies to Frankfurt and Munich – both routes were among the most used international connections in 2025, surpassed only by London-Gatwick and Amsterdam. Added to that are Air France to Paris-Charles de Gaulle and KLM to Amsterdam, often with Embraer jets such as the Embraer E190 of their regional subsidiaries, such as KLM Cityhopper. In addition, TAP Air Portugal flies to Lisbon, Turkish Airlines to Istanbul and Brussels Airlines to Brussels. With Lufthansa and its Star Alliance partners, Air France, KLM and Air Europa from SkyTeam and Iberia from oneworld, all three big alliances are represented.

The picture is rounded out by low-cost and leisure airlines such as Wizz Air, easyJet and Eurowings, some of which fly only seasonally. An exotic is the seasonal United Airlines connection to Newark, which started in summer 2025 – introduced with a Boeing 757, a type you hardly see otherwise in Bilbao.

Schedules change every season. Which routes and types are actually flying right now, you see most reliably on the arrivals and departures boards or in a flight tracker.

Spotting in Bilbao: no visitors’ hill, but options

Unlike Munich or Barcelona, Bilbao has no official visitor area and no observation deck. The local spotter scene therefore uses public places around the airport. Best known are positions under the approaches to 30 and 12, places along the departure routes and an elevated site from which you overlook a large part of the airport including the apron. Because some of these spots lie at gas stations, commercial areas or sports fields, this applies especially here: stay on public paths, don’t disturb anyone at work and keep your distance from the fence.

In Spain, you should also know the customs for dealing with security forces. What is allowed there, how to behave during a check and which documents you should carry is summarized in the article Spotting in Spain. General principles are in the article Is plane spotting allowed?.

Because there is no visitor park with fixed opening hours, your day depends on the light even more than elsewhere. The main runway runs from southeast to northwest; depending on location and season, you get approaches in backlight or with the sun behind you. So check before every visit when the sun is favorable at your chosen spot – and whether it shows up at all.

What you get in front of your lens

Widebody aircraft are the exception in Bilbao. The picture is shaped by the A320 family in all variants: the classic Airbus A320 and the A320neo at Vueling, plus, depending on airline and rotation, A319, A321 or A321neo. If you want to tell the variants apart reliably, the article A320neo or ceo? has the key features, and the article on the A320 family helps with the A319, A320 and A321.

Variety comes from the Embraer jets of Air France and KLM, Boeing 737-800s of airlines such as Air Europa or the seasonally flying Norwegian as well as occasional turboprops and business aircraft.

Getting there and location

The airport lies north of Bilbao in the Txorierri valley, in the municipalities of Loiu and Sondika. From downtown, you’re there in about a quarter of an hour by car, depending on traffic. By public transport, the Bizkaibus A3247 runs between the airport, downtown and the Termibus bus station, according to timetable information every quarter hour. Other bus lines connect the airport directly with San Sebastián and other Basque cities. There is no rail link; an extension of the metro has been discussed for years.

For spotters, a rental car is often still the most practical choice because the spots are spread around the runway ends and there are hills and roads without sidewalks between them. If you come by bus, think carefully beforehand about which places are reachable on foot.

Expansion and future

With more than seven million passengers, the terminal is well above the capacity it was once designed for. Plans for expansion have existed for a long time – as early as 2009, an expansion to eight million passengers was announced, which then took its time. A new master plan for Bilbao has since been approved, which provides for additional jet bridges, among other things, and wants to move the cargo area closer to the passenger terminal. When which construction phases are finished, you should look up in the operator’s current announcements before a visit – construction sites can also change known spots and sight lines.

Bilbao in comparison

In Spain, Bilbao is one of the mid-sized airports – much smaller than Madrid or Barcelona, but of an order of magnitude comparable to Seville or Valencia. Across the French border, Bordeaux Airport is the nearest larger destination on the Bay of Biscay.

If you’re planning a Spain tour, combine Bilbao well with Madrid: in the article Plane spotting at Madrid-Barajas, you’ll find the right spots for the capital, and at the La Muñoza spot you then see the long-haul you’re missing in Bilbao. For aviation history, the Museo del Aire in Madrid-Cuatro Vientos is also worthwhile.

Conclusion

Bilbao Airport is a place where aviation and architecture come together. Calatrava’s La Paloma terminal and the tower give it a face you recognize in every photo. Operationally, BIO is pleasantly manageable: one main runway, mostly runway direction 30, Vueling as the biggest user and feeders from Lufthansa, Air France, KLM and other network airlines.

What Bilbao demands is planning. Without a visitor park, you have to choose your spots yourself, and the Atlantic weather doesn’t cooperate every day. If you check wind, clouds and light beforehand and follow the rules at the fence, you take home pictures from the Basque Country that can’t be made anywhere else.
