Porto Airport (OPO), officially Francisco Sá Carneiro Airport, is about 11 km north of the city centre and has one of the most convenient metro connections of any European airport. Metro line E — the violet line — runs directly from the airport to the heart of Porto and onwards to the waterfront in under 30 minutes. Buses and taxis round out the options for those who need a more flexible or door-to-door service.
Metro line E (violet): the clear first choice
The Linha E (violet) of Porto's Metro is the fastest, cheapest and most reliable way into the city. The airport has its own metro station — Aeroporto — accessible from inside the terminal building via a clearly signed walkway. Trains run every 20–30 minutes (more frequently during peak hours) from around 06:00 until just after midnight.
Key stops along the route include Trindade, Porto's main metro interchange in the city centre, and Aliados, close to the Câmara Municipal and the commercial heart of the city. From Trindade you can change to other metro lines (A, B, C, D, F) to reach Campanhã (the main rail station for intercity connections), Boavista, the Zoo or the beaches further north. The full journey from the airport to Trindade takes around 25–30 minutes.
Tickets use Porto's Andante card system. You can buy the card (which has a small one-off charge) and load a zone-appropriate travel credit at the machines in the airport station. The airport is in zone 4 (Z4) from the central zones, so an Andante Tour day card or a loaded trip card covering Z4 is what you need. Tap in at the validator before boarding and tap out at your destination — the system requires both.
Tip: If you plan to use the metro several times during your stay, an Andante Tour 24h or 72h card covers unlimited travel within the included zones and is excellent value. Buy it at the airport station before you travel into the city.
Night arrivals: what happens after midnight
The metro closes shortly after midnight. If you arrive on a late-night flight — particularly common on budget routes from northern Europe — you will find the metro shut and a taxi or rideshare will be your only public option. Plan for this if you are arriving after around 23:30 and budget accordingly.
Bus options
STCP (Sociedade de Transportes Colectivos do Porto) and inter-city bus operators serve the airport, though for city-centre travel they are generally slower than the metro. Bus routes connecting the airport to central Porto run through suburban streets and are subject to traffic delays, making journey times variable. They are most useful for destinations not well served by the metro, or as a budget option for those already familiar with the Porto bus network.
Long-distance coach operators also serve the airport, with services to cities across Portugal and sometimes to Spain. If you are connecting to Braga, Viana do Castelo or other northern Portuguese towns, check whether a direct coach from the airport is available, as it may save a trip into the city first.
Taxi
Taxis are available at the marked rank outside arrivals. The drive to central Porto takes 15–25 minutes in normal traffic, though the VCI ring road and the approaches to the city centre can become congested during peak commuter hours and at weekends when Porto is busy with visitors. Fares are metered; there is a legitimate airport supplement added at the start of the trip, which is normal practice.
For a solo traveller, the metro is much cheaper. For two or more people travelling together, particularly with luggage or late at night, a taxi becomes more attractive.
Rideshare: Uber and others
Uber operates in Porto and works well from the airport. Book via the app and you will be directed to a designated pick-up area (typically a short walk from the main taxi rank — follow signs or check the app for the exact location). Bolt is also popular in Portugal and often competitive on price. Pre-trip fare estimates in the app help you budget in advance.
Rental car
Car hire desks are in the terminal building. Porto's city centre is compact and, like most historic Portuguese cities, has narrow streets, cobblestones, steep hills and limited parking — a car is more hindrance than help for city sightseeing. However, a hire car opens up the Douro Valley wine country (a UNESCO World Heritage landscape), the Minho region and the Costa Verde coastline, all of which are difficult or slow to reach by public transport. If that is part of your plan, picking up the car at the airport makes sense.
Travelling onward from Porto
Porto's Campanhã station (reachable by metro via Trindade) is the main intercity rail hub for connections south to Lisbon (under 3 hours by Alfa Pendular express), north to Vigo and into Spain, and east along the Douro valley. For those using Viamo's wider network of route guides, connections towards Madrid or onward into Europe are covered in detail in the relevant route articles.
Getting back to the airport
From the city centre, board the metro line E at Trindade or Aliados and ride out to the Aeroporto station. Allow 30 minutes plus terminal time. Porto Airport handles a lot of budget traffic from across Europe, and the security queues on popular routes can be substantial, particularly on Monday mornings and Sunday evenings. Arriving 90 minutes before a short-haul flight is a sensible minimum; 2 hours is safer if you are checking bags.
