Bilbao Airport sits in the municipality of Loiu, about nine kilometers north of downtown Bilbao across the Artxanda ridge, and it is the primary commercial airport for the whole Basque Country, which is why finding cheap flights to Bilbao from the UK, Ireland and continental Europe is easier than the city’s size suggests. The absence of a terminal rail link means your ground transport has to be planned around highway timetables. Public transport maps from Metro Bilbao and regional rail operator Euskotren confirm that while commuter rail lines traverse the neighboring Txorierri valley, no passenger rail tracks reach the airport terminal itself. An underground rail connection from Sondika has been discussed for decades, but on your travel day, every transit link from Loiu moves by road.
Ground Transport: The Airport Bus and City Transfers
The primary public transit connection between Bilbao Airport and downtown is Bizkaibus Line A3247 (Bilbao – Aireportua). Operated by the provincial transit authority of Biscay, this dedicated express bus links the terminal to the city center via the Artxanda road tunnels, providing a reliable and low-cost airport transfer:
- Route and City Stops: Inbound from the airport, buses leave the arrivals curb on Floor 0 and stop at Alameda Recalde, Plaza Moyúa and Gran Vía 79 before terminating at Bilbao Intermodal, the central bus station still widely called Termibus. Outbound, they start at Intermodal, pick up at Plaza Moyúa and Alameda Recalde, then run non-stop to the departures concourse on Floor 3.
- Frequency: The airport’s own transport page lists Line A3247 as running every 15 minutes in both directions, on a clock-face pattern: departures from the airport at :10, :25, :40 and :55 past the hour, and departures toward the airport at :00, :15, :30 and :45. The journey between the airport and Bilbao Intermodal takes approximately 15 to 25 minutes depending on traffic congestion entering the city center. Printed provincial timetables for this line have also circulated in a half-hourly version, so if your onward connection is tight, read the departure board on the day rather than trusting any frequency published in advance.
- Operating Hours and Directional First/Last Departures: The two directions do not keep the same hours, and the gap matters if you are booking a late arrival or a dawn departure. Toward the airport, buses run from 05:00 to 22:00. From the airport into the city, they run from 06:10 to 23:40. Fares can be paid via single-ride paper tickets purchased from the airport ticket booth or driver, but using a rechargeable contactless Barik transport card substantially reduces the cost per trip.
- The Txorierri Valley Link (Line A2153): Travelers heading to suburban business parks or local towns in the valley rather than central Bilbao can board Bizkaibus Line A2153 (Bilbao – Txorierri – Larrabetzu), which stops at the airport and connects to neighboring municipalities including Sondika, Derio, Zamudio, and Lezama, where interchanges with Euskotren Line E3 commuter trains are available.
- The Two Buses Most Guides Miss: A3247 is not the only scheduled coach at this curb. Autobuses La Unión runs Line A3720 from the airport arrivals level direct to Vitoria-Gasteiz, so travelers heading for Álava or Rioja do not have to route through central Bilbao at all. Lurraldebus Line DG12 also leaves the airport for the Mondragón area, with departures listed at 6:45, 9:45, 12:45, 15:45, 19:15 and 23:15 daily. Both are listed on the airport’s own bus page and neither appears in most English-language guides to Bilbao.
- Official Airport Taxis: Licensed taxis work from the rank immediately outside arrivals on Floor 0. There is no flat airport tariff: they run on regulated meters, with an airport supplement added to the metered fare. The journey into the centre takes fifteen minutes in normal traffic.
For anyone staying near Plaza Moyúa, the Guggenheim or the Casco Viejo, A3247 is the transfer to take. If your flight lands after the last inbound bus at 23:40, a licensed taxi from the rank is the only way out of the terminal.
The San Sebastián Coach: Flying to Bilbao for Donostia and Rioja
A large share of the passengers landing at Loiu are not going to Bilbao at all. They are heading for Donostia-San Sebastián, or south to the vineyards of La Rioja. San Sebastián’s own airport carries very little, which leaves Bilbao as the international door to the whole eastern Basque coast.
The connection is direct, and it is the reason this airport works for a trip that never touches Bilbao:
- The Lurraldebus Direct Coach (Line DO04): Operated by Avanza Movilidad Gipuzkoa under the Lurraldebus network, Line DO04 connects Bilbao Airport directly to San Sebastián bus station (Donostiako Autobus Geltokia). The coach departs directly from the airport arrivals platform on Floor 0, taking approximately 1 hour and 15 minutes to 1 hour and 20 minutes along the AP-8 toll highway.
- Frequency, and It Is Hourly: This is the number to plan around, because it is thinner than most travelers assume for an airport link. The airport lists DO04 as running every 60 minutes. Departures from San Sebastián toward the airport run from 05:00 to 21:00. Departures from the airport toward San Sebastián run from 07:45 to 22:45 daily, with an earlier weekend start at 06:45. Miss one and you wait an hour, so check your inbound arrival time against that last 22:45 departure before you book an evening flight.
- The Zarautz Intermediate Stop: DO04 runs via Zarautz, the surf town on the Gipuzkoan coast, which makes it the one airport coach in the region that drops you at a beach on the way. If Zarautz is your destination rather than a waypoint, name it when you buy the ticket.
- Reaching La Rioja and Vitoria-Gasteiz: For Logroño and the wine towns of Rioja Alta, take Bizkaibus Line A3247 to Bilbao Intermodal (20 minutes) and transfer to an ALSA or Cuenca del Ebro coach (1 hour 45 minutes), or rent a car at the airport (1 hour 15 minutes via AP-68). For Vitoria-Gasteiz, do not route through the city at all: Autobuses La Unión Line A3720 leaves from the airport arrivals level, and driving takes about 45 minutes.
If San Sebastián is the trip, the coach from the Loiu arrivals curb beats flying into Madrid or Barcelona and transferring to a regional train.
The Carrier Landscape: Who Actually Flies to Bilbao
Bilbao is the dominant commercial airport in northern Spain. Aena’s own traffic statistics record that it handled 7,062,681 passengers in 2025 (a 4.2 percent increase over 2024’s 6,777,267 passengers), setting an all-time record driven by international expansion. A total of 37 airline companies operate scheduled and seasonal flights at the airport.
The carrier ecosystem at BIO is anchored by two established low-cost bases operating alongside European legacy flag carriers:
- Vueling Base: Vueling is the largest carrier at Bilbao Airport, maintaining its second-largest base in Spain after Barcelona El Prat. Vueling permanently stations eight Airbus A320 aircraft at Loiu and operates over thirty routes. From the UK, Vueling operates year-round flights connecting Bilbao to London Gatwick. Domestically, Vueling runs high-frequency trunk lines to Barcelona, Madrid, Palma de Mallorca, Menorca, Ibiza, Seville, Malaga, Alicante, Valencia, Santiago de Compostela, A Coruña, Tenerife North, Tenerife South, Gran Canaria, Lanzarote, Fuerteventura, and La Palma, alongside European routes to Paris Orly, Amsterdam, Milan Malpensa, Florence, and Rome Fiumicino.
- Volotea Base: Volotea maintains an operational base at Bilbao Airport with two permanently stationed Airbus A320 aircraft. Volotea operates 21 routes across Spain, Italy, Portugal, Greece, and Morocco, including seasonal leisure services to Olbia, Naples, Palermo, Florence, Rome, Porto, Athens, and Marrakech, alongside domestic links to Seville, Malaga, Valencia, Alicante, A Coruña, and the Balearic Islands.
- From the United Kingdom and Ireland: Direct non-stop flights from the UK and Ireland are operated by four main carriers. British Airways flies year-round from London Heathrow. easyJet operates scheduled services from London Gatwick, Manchester, and Bristol. Vueling flies year-round from London Gatwick. Aer Lingus operates direct scheduled services connecting Bilbao to Dublin.
- European Legacy Flag Carriers: Full-service European network carriers provide daily links between Bilbao and their continental hubs. Lufthansa operates daily flights to Frankfurt and Munich; Air France flies to Paris Charles de Gaulle; KLM operates daily flights to Amsterdam Schiphol; Brussels Airlines connects to Brussels; TAP Air Portugal flies to Lisbon; Swiss International Air Lines operates to Zurich; Eurowings flies to Düsseldorf and Stuttgart; Norwegian operates seasonal flights to Oslo; and Wizz Air runs routes connecting Bilbao to Warsaw and Bucharest.
- Domestic Spanish Operators: Alongside Vueling and Volotea, Spain’s network carriers maintain high-frequency domestic trunk links. Iberia and Air Nostrum operate multiple daily flights to Madrid Barajas and regional islands. Air Europa connects Bilbao to Madrid and Palma de Mallorca. Binter Canarias operates scheduled flights linking Bilbao directly to Gran Canaria and Tenerife.
- Transatlantic Long-Haul Connections: There are currently no direct non-stop transatlantic passenger flights from the United States or Canada into Bilbao Airport. North American travelers connect one-stop through a European hub: London Heathrow on British Airways, Madrid on Iberia, Paris Charles de Gaulle on Air France, Frankfurt on Lufthansa, Amsterdam on KLM, or Dublin on Aer Lingus.
Because many low-cost routes (especially on Volotea and easyJet) operate on seasonal schedules running from April to late October, winter travelers will find a consolidated network centered on trunk routes to Madrid, Barcelona, London, Paris, Frankfurt, and the Canary Islands.
The Four Doors into the Basque Country
Four airports sit within about ninety minutes of each other here, and almost nobody lays them out honestly. Bilbao is usually the right answer. It is not always:
- 1. Bilbao Airport (BIO – Loiu): Located 9 km north of Bilbao. The primary international gateway with the highest flight volume, 37 airlines, major bases for Vueling and Volotea, and direct coaches to San Sebastián. This is the default door for travelers arriving from the UK, Ireland, and northern Europe.
- 2. San Sebastián Airport (EAS – Hondarribia): Located 22 km east of San Sebastián in the border town of Hondarribia, next to the French frontier and the Bidasoa river. Its short 1,754-meter runway restricts jet operations. However, it is served by regular scheduled flights on Iberia (to Madrid), Vueling (to Barcelona), Binter Canarias (to Gran Canaria and Tenerife North), and Volotea (to Seville year-round, plus seasonal Malaga, Menorca and Palma, with a new Florence route from 21 September 2026). The one link that matters most to British readers is not seasonal: BA CityFlyer has flown London City to San Sebastián since July 2022, and it runs year-round. British Airways also adds seasonal Scottish services, from Edinburgh and Glasgow, in summer. If you find a well-priced connection via Madrid or Barcelona, landing at EAS puts you twenty minutes from downtown San Sebastián via Lurraldebus Line E20 or E27.
- 3. Vitoria Airport (VIT – Foronda): Located 9 km northwest of Vitoria-Gasteiz and 65 km south of Bilbao. Known primarily as a leading Spanish air cargo hub, Vitoria also maintains regular scheduled passenger operations. Ryanair is the primary passenger carrier, operating scheduled routes connecting Vitoria to Alicante, Malaga, Palma de Mallorca, Seville, Brussels Charleroi, and Milan Bergamo. Foronda has also rebuilt a domestic board it had not held in two decades: Volotea flies to Madrid, Barcelona and, since June 2026, Menorca, and Binter links Vitoria to Gran Canaria. Watch the season, though — the Volotea Madrid and Barcelona services pause over the summer and their 2026 operating window closes on 23 October, so an autumn booking that assumes a year-round domestic link will not find one. If traveling on budget routes from Charleroi or Bergamo, flying into Vitoria and taking a regional bus north can yield substantial savings.
- 4. Biarritz Pays Basque Airport (BIQ): Across the French border, about 50 km northeast of San Sebastián, and for some UK readers the cheaper door to it. Air France flies from Paris; Ryanair (London Stansted, Dublin, Brussels Charleroi), easyJet (London Gatwick and French regional airports) and Transavia add seasonal low-cost routes. ALSA and FlixBus coaches reach San Sebastián bus station in 45 to 60 minutes, or take French bus Line 3 to Hendaye and cross on Euskotren.
- 5. Seve Ballesteros-Santander Airport (SDR): A hundred kilometres west, in Cantabria, and a Ryanair base: London Stansted, Edinburgh, Birmingham, Manchester, Dublin, Brussels Charleroi, Rome and Vienna. ALSA coaches run to Bilbao Intermodal in 75 to 90 minutes, which makes it a real backup when Bilbao fares spike.
The Sea Door: Brittany Ferries to Bilbao and Santander
For travelers transporting vehicles, traveling with pets, or carrying oversized sporting gear like surfboards, the sea door provides a direct alternative to commercial flights. Brittany Ferries operates scheduled year-round passenger and vehicle ferry crossings from Portsmouth International Port to the Port of Bilbao (located in Zierbena, fifteen kilometers west of Bilbao) and to Santander.
The maritime connection operates on structured weekly schedules:
- Portsmouth to Bilbao: The route runs all year on the E-Flexer cruise ferry Galicia, but not at the same rate all year, and this is the detail an autumn or winter booking turns on: two sailings a week from roughly late March to the beginning of November, and one a week — a Tuesday night departure from the UK — through the winter. The crossing takes approximately 32 to 36 hours across the Bay of Biscay as a two-night voyage.
- Portsmouth to Santander: Up to two weekly sailings, on the LNG-powered sisters Salamanca and Santoña, taking roughly 31 to 33 hours. Unlike the Plymouth service to the same port, this one does not take a winter break: from mid-November to mid-March it settles into a weekly Thursday-night departure. Plymouth and, from Ireland, Rosslare are the other doors into the same two Spanish ports, which is worth knowing if Portsmouth is the wrong side of the country for you.
While the ferry crossing takes significantly longer than a two-hour flight, it avoids baggage restrictions, eliminates car rental surcharges in Spain, and allows road-trip travelers to drive directly into the Basque countryside.

The Basque Calendar: Rain, Harvests, and Aste Nagusia
Bilbao’s travel calendar and pricing patterns differ sharply from the sun-and-beach destinations of the Mediterranean coast. Flight fares and hotel availability follow distinct regional dynamics driven by climate, festivals, and gastronomic seasons.
- Atlantic Climate and Rainfall Normals: According to official climatological normals (1981–2010 baseline) from the Spanish State Meteorological Agency (AEMET) for the Bilbao Aeropuerto weather station (Station 1082), Bilbao receives an average annual precipitation of 1,134 mm spread across 128 rainy days per year. November is historically the wettest month, averaging 147 mm of rainfall, while July is the driest month, averaging 50 mm. A light drizzle known locally as siri-siri is common throughout the year, meaning packing a waterproof jacket is essential in any season.
- The Autumn Gastronomy Window (September–November): Autumn is widely considered the best time to visit the Basque Country. The September and October grape harvests for crisp Basque white wine (txakoli) take place along coastal hills, wild forest mushroom foraging peaks in the mountains, and summer crowds thin out. Flight fares from the UK and Europe soften considerably compared to July and August peaks.
- Aste Nagusia / Semana Grande (Mid-August): Bilbao’s biggest annual cultural celebration, Aste Nagusia (The Great Week), begins on the first Saturday after August 15 and runs for nine days. In 2026 that means 22 to 30 August, so if you are reading this in the last week of the month, it is happening as you read. The city fills with open-air concert stages, festive wooden bars (txosnas) along the riverbanks, nightly international fireworks competitions, and traditional Basque sports. Hotel rooms across Bilbao sell out months in advance, and flight fares into BIO reach their highest peak of the year. If you want to be there for the next one, start looking around four months out; if you prefer quiet sightseeing, aim at any other week in the year.
- The Mild, Wet Winter (December–February): Winter in Bilbao is oceanic and mild, with average daily temperatures hovering around 9.3°C in January (average highs of 13°C and lows of 5°C). Snow is rare at sea level, but winter brings frequent Atlantic rain fronts. Outside of Christmas and New Year, winter represents the cheapest season for flight tickets and boutique accommodation.
Money and Time: The Pintxo and Menú del Día Conventions
Spain uses the Euro (EUR) and operates on Central European Time (CET/CEST). Navigating daily food expenses and commercial arrangements in Bilbao involves understanding several distinctive Basque customs:
- The Pintxo Commercial Mechanism: Dining in Basque bars revolves around pintxos—small culinary creations displayed in elaborate arrangements along the bar counter. Unlike in parts of southern Spain (such as Granada or Jaén) where a small tapa is served complimentary with a drink, in the Basque Country every pintxo is an individually priced commercial item. Cold pintxos are taken from the counter on a plate provided by the bartender, while warm pintxos (pintxos calientes) are ordered from a chalkboard menu and prepared fresh in the kitchen. You keep a running tab with the bartender and settle before leaving. The convention is one small drink and one or two pintxos per bar, then move on.
- The Menú del Día: Traditional restaurants serve a weekday fixed-price lunch, the menú del día, between roughly 13:30 and 15:30 Monday to Friday: first course, second course, bread, dessert, and a bottle of house wine or water included.
- Tipping Customs: There is no percentage convention as in North America. Round up to the nearest euro in bars, leave small change for attentive table service.
Booking Mechanics and Entry Requirements
Spain is in the European Union and the Schengen area, and the short-stay rule is the familiar one: British, US, Canadian and Australian passport holders travel without a visa for up to 90 days in any 180-day period, and days spent anywhere else in Schengen in the preceding 180 count toward that total. Two passport conditions are worth checking before you book rather than at the gate. The UK government states the date of issue must be less than ten years before the day you arrive, and the expiry date at least three months after the day you plan to leave the Schengen area — the ten-year rule catches people whose passports were renewed early and carry extra months.
The border process itself has changed. The EU Entry/Exit System is now in operation, and UK guidance for Spain says that on entering the Schengen area for a short stay you may need to register biometric details, including fingerprints and a photograph. Expect that first registration to add time at the desk. The European Travel Information and Authorisation System, ETIAS, is a separate scheme still to come: it will require a paid pre-travel authorisation obtained online before boarding. It is not in force yet, and no rollout date should be treated as final until the Commission confirms one. Check current requirements before you book your flight.
The Final Caveat
The one operational mistake travelers make here is assuming a European airport comes with a railway attached. There is no train under Calatrava’s terminal. Everything leaves Loiu by road — the Bizkaibus express into the centre, or the hourly coach down the motorway to San Sebastián. Check the times against your flight before you touch down, and the airport with no train turns out to be the right door into Basque Country.
FAQ
How do I get from Bilbao airport to the city centre?
The fastest and most economical public transport option is Bizkaibus Line A3247 (Bilbao – Aireportua), which departs from the arrivals curb on Floor 0. The bus stops at Alameda Recalde, Plaza Moyúa, and Gran Vía before terminating at Bilbao Intermodal, taking approximately 15 to 25 minutes depending on traffic. Taxis operate on regulated meters from the outside rank.
Is there a train from Bilbao airport?
No. Bilbao Airport has no train, tram, or metro station connected to its passenger terminal. All public ground transport operates via road coach and bus services from the terminal building.
Can you fly to Bilbao and go straight to San Sebastián?
Yes. The Lurraldebus Line DO04 coach operated by Avanza departs directly from the airport arrivals platform on Floor 0, taking passengers straight to the San Sebastián bus station in approximately 1 hour and 15 minutes to 1 hour and 20 minutes without needing to enter downtown Bilbao.
When is the cheapest time to fly to Bilbao?
Flight fares are generally lowest during the winter low season from November through February (excluding Christmas and New Year), when tourist demand is soft and Atlantic rainfall is higher. The autumn shoulder months of October and November also offer competitive airfares.
