How to get to Portugal: airports, flights and border crossings

Portugal has three mainland airports that matter to visitors, plus two island groups. Lisbon (LIS) is the default: it takes the widest range of long-haul flights and puts you 20 minutes by metro from Baixa. Porto (OPO) is smaller but well connected to European hubs and is the right choice if your trip is the north, the Douro or Galicia. Faro (FAO) serves the Algarve and fills with seasonal flights from April to October.

Madeira (FNC) and the Azores (PDL on São Miguel, plus Terceira and Faial) are separate trips, not add-ons to a mainland week. Both have year-round flights from Lisbon and Porto, and seasonal routes from other European cities.

If you are coming from the US, nonstop service to Lisbon runs from several East Coast hubs and takes roughly seven hours; West Coast travellers usually connect through a European hub. From the UK and Ireland, Lisbon and Porto are short-haul, roughly two and a half hours from London. From Canada, Australia and New Zealand, expect at least one connection, usually in a European hub or the Middle East.

Book long-haul flights three to six months ahead for summer (June–August) and around Christmas, when Lisbon and Porto fill with both tourists and Portuguese returning home. Shoulder months — late April to early June and September to mid-October — usually give the best balance of price and weather.

Low-cost carriers dominate short-haul routes from the UK, Ireland and elsewhere in Europe, often into Porto or Faro rather than Lisbon. Baggage rules are strict and airport choices can be secondary ones, so check which airport you are actually landing at before booking a transfer.

For the islands, book early in summer: seats to Madeira and the Azores are limited and prices rise sharply in July and August.

Portugal has one land border, with Spain, and it is open. Road crossings on the main motorways and the older routes are routine; there are no regular passport checks, though police can stop vehicles. Cross-border trains and buses link Lisbon and Porto with Spanish cities, and buses are often cheaper and more frequent than trains on these routes.

There is no ferry from the UK, Ireland or North America to mainland Portugal. Ferries serve the islands and local routes: Madeira has connections to Porto Santo, and the Azores have inter-island services. If you want to arrive by sea from the UK, you would need a cruise or a route via Spain.

Travellers arriving from another Schengen country by land or air generally pass through without border formalities, but carry your passport anyway — it is required ID.

US, UK, Canada, Australia, New Zealand and Irish passport holders can enter Portugal visa-free for up to 90 days in any 180-day period as part of Schengen. Your passport should be valid for at least three months beyond your planned departure and issued within the last ten years. Check current rules before you fly, since they can change.

At Lisbon, the metro is the cheapest way into the centre and runs until around 1am; taxis and ride-hailing are quicker at night. Porto's metro connects the airport to the centre and to Campanhã for trains. At Faro, a bus or taxi reaches the town, but if you are heading to Lagos or Albufeira, book a transfer or pick up a car at the airport.

Sort three things before departure: travel insurance that covers medical costs and any activities you plan, a SIM or eSIM for data on arrival, and a card or cash in euros for the first day. Many Portuguese motorways use electronic-only tolls, which matters if you are driving across the border from Spain.

Booking into Lisbon when your trip is the Algarve or the north wastes a day in transfers. Assuming you can reach Madeira or the Azores by ferry from the mainland is another; there is no such route. And treating Portugal as a small country ignores the distances: Lisbon to the Algarve is about three hours by car, Lisbon to Porto about three hours by train.

Finally, do not leave entry paperwork to the airport. Even visa-free travellers can be asked for proof of onward travel, accommodation and enough funds, so have those ready on your phone.
