Quick answer. At Porto's Francisco Sa Carneiro (OPO), use a Multibanco (MB) ATM: Portugal's shared bank network (Caixa Geral, Millennium BCP, Santander Totta, Novo Banco and the rest all sit on it) dispenses euros at the interbank rate with no operator surcharge. The machines to avoid are the standalone blue-and-white Euronet ATMs, which push DCC and add fees. Always decline DCC and choose euros. Portugal has no Bank of America Global ATM Alliance partner, but because Multibanco adds no surcharge, a Wise or Charles Schwab card lands you at essentially the mid-market rate. Getting into town is easy: the Metro Line E (violet line) runs straight from the terminal to central Porto (Trindade/Aliados) in about 30 minutes for a couple of euros on an Andante card.
Where to get euro at OPO
The key Porto fact is that Portugal's shared Multibanco (MB) network gives the interbank euro rate with no operator surcharge at almost any bank ATM, while the standalone Euronet machines and the exchange counter are the traps. The cost math below assumes you withdraw or exchange the equivalent of $100 in euros.
| Option | Where | Markup | Total Cost |
|---|---|---|---|
| Multibanco (MB) bank ATM (OPO terminal) | Arrivals | Interbank rate, no operator surcharge | ~$100 |
| Multibanco ATM + Schwab / Wise (no FX fee) | Arrivals | Interbank rate, no fees | ~$100 |
| Multibanco ATM with a BoA card (no Alliance here) | Arrivals | Interbank rate + BoA 3% non-network fee | ~$97 |
| Euronet standalone ATM (blue-and-white) | Terminal | DCC pitch + its own fees | ~$88-93 |
| Exchange counter / accepting DCC | Arrivals / anywhere | Several % off interbank, or +5-10% DCC | ~$90-94 |
Where to find the Multibanco ATMs (and avoid Euronet) at Porto (OPO)
Francisco Sa Carneiro (OPO) is northern Portugal's main airport, about 11 km north of central Porto, with a single passenger terminal. The key money fact in Portugal is the Multibanco (MB) network: nearly every Portuguese bank (Caixa Geral de Depositos, Millennium BCP, Santander Totta, Novo Banco, BPI and others) shares one interbank ATM system, and MB machines give the real euro rate with no operator surcharge for foreign Visa and Mastercard withdrawals. That makes Porto one of the easiest airports in Europe for cash: look for the MB / Multibanco logo, withdraw, and you get the interbank rate. The trap is the standalone blue-and-white Euronet ATMs in the terminal, which are not part of Multibanco: they push dynamic currency conversion and their own fees. Portugal has no Bank of America Global ATM Alliance partner, but with no Multibanco surcharge, a Wise or Charles Schwab card effectively lands you at the mid-market rate. Whatever you use, decline DCC and choose euros.
Main Terminal (single passenger terminal)
TAP Air Portugal, Ryanair, easyJet, Wizz Air, Vueling and other European and connecting carriers, plus seasonal long-haul services. The single terminal handles all flights, with the Metro station directly beneath
In the arrivals area, look for a Multibanco (MB) bank ATM (Caixa Geral, Millennium BCP, Santander Totta and others all share the network) and avoid the standalone blue-and-white Euronet machines. Insert a foreign Visa or Mastercard, decline DCC, and choose euros; Multibanco adds no operator surcharge, so a Wise or Schwab card lands you at the interbank rate. Withdraw a small float, then take the escalators down to the Metro Line E station for the ride into central Porto.
Do you actually need cash at Porto (OPO)?
Mostly no. Porto is card-friendly across restaurants, shops and the Metro (on the Andante card), so you need little cash. A small euro float helps for markets, small tascas, port-cellar tips and the odd cash-only spot. Here is what works on a card and where a little cash helps:
Metro Line E (violet line) (~2 EUR on an Andante card (Z4)): Runs directly from the airport station beneath the terminal to Trindade/Aliados in central Porto in about 30 minutes; buy an Andante card at the machines and load a Z4 ticket. Cheapest and most reliable.
Uber / Bolt (~20-25 EUR to central Porto): Both ride apps operate at OPO and bill your card directly; about 20-30 minutes to the center depending on traffic.
Taxi (~20-25 EUR to central Porto): Metered taxis from the rank outside arrivals; Porto taxis generally accept cards. A small surcharge may apply for luggage or night rides.
Airport shuttle / hotel transfer (Varies (arranged in advance)): Some Porto and Douro Valley hotels arrange a transfer billed to the room or card, convenient with luggage or for onward wine-country trips.
⚠ DCC trap. When the ATM or terminal asks if you want to be charged in your home currency instead of the local currency, always decline and choose the local currency. Accepting locks in a 3-13 percent markup that your no-FX-fee card cannot undo. Full DCC explainer →
Frequently Asked Questions
Do I need cash to get from Porto (OPO) to Porto?
No. Metro Line E (violet line) accepts contactless. Most taxis accept cards. Uber and other apps are card-only.
Can I order euro before flying?
Yes. CEI Currency Exchange ships physical euro to your US address in 2-5 days at rates well below airport counters. Order 50-100 euro for taxis and tips on day one.
What is Multibanco and why does it matter at Porto Airport?
Multibanco (branded MB) is Portugal's shared interbank ATM and payments network, used by essentially every Portuguese bank. For a traveler it means almost any bank ATM gives the same fair deal: the interbank euro exchange rate with no operator surcharge on foreign-card withdrawals. So at Porto Airport you do not need to hunt for a particular bank; just look for the MB / Multibanco logo, decline DCC, and choose euros. The one exception to avoid is the standalone blue-and-white Euronet machines, which are not Multibanco and add DCC and fees. Because Multibanco adds no surcharge, a Wise or Charles Schwab card lands you at essentially the mid-market rate.
How do I get from Porto Airport into the city?
The Metro do Porto Line E (the violet line) runs directly from the airport station beneath the terminal into central Porto, reaching Trindade (the main interchange near Aliados) in about 30 minutes. Buy a reusable Andante card at the machines (a small one-off cost) and load a Z4 zone ticket, roughly a couple of euros; tap in and out. It is the cheapest and most reliable option. A taxi or Uber/Bolt into the center runs about 20 to 25 euros and takes 20 to 30 minutes depending on traffic; the ride apps bill your card directly.
Should I use the exchange counter or Euronet at Porto Airport?
No to both. The currency-exchange counter quotes a euro rate worse than a bank ATM, and the standalone blue-and-white Euronet ATMs push dynamic currency conversion and add their own fees. A Multibanco (MB) bank ATM in the terminal gives the interbank rate with no operator surcharge; that is the cheapest way to get euros at OPO. Always decline any offer to be charged in your home currency (DCC) and choose euros, letting your own bank handle the conversion.
Is there a Bank of America Alliance partner at OPO?
No. Portugal has no Bank of America Global ATM Alliance partner, so a BoA debit card pays BoA's 3 percent non-network fee. But because the Multibanco network adds no operator surcharge, the fix is simple: use a no-foreign-transaction-fee card. A Wise card gives the interbank rate with no markup, and a Charles Schwab card adds no FX fee, so either one at a Multibanco ATM at Porto lands you at essentially the mid-market rate.
