How to find cheap flights Barcelona to Porto
Three airlines compete on this route, which keeps fares low most of the year. What actually moves the price:
- Book 3–6 weeks ahead. BCN to OPO holds steady pricing; last-minute fares spike hard on summer weekends.
- Fly midweek. Tuesday and Wednesday are reliably the cheapest days; Friday and Sunday carry a premium.
- Target the low season. January, February and November are the bargain months; June–September and Easter week are the peaks.
- Stay flexible on dates. Moving your departure by one day often cuts the fare by 25–30%. Use a flexible-date search.
Airports: what to know on both ends
Barcelona El Prat (BCN) — Ryanair operates from Terminal 2, while Vueling and TAP use Terminal 1. Check your terminal before you travel: they’re separate buildings connected by a free shuttle. The R2 Nord commuter train serves T2 and reaches central Barcelona in about 25 minutes; the Aerobús runs to both terminals every few minutes.
Porto Airport (OPO) — Officially Francisco Sá Carneiro, about 11 km northwest of the city. It’s compact, efficient and rarely crowded. Metro line E (violet) runs straight to Trindade in the centre in roughly 30 minutes for a couple of euro — one of the easiest airport transfers in Europe. Taxis cost around €25–30.
Airlines flying Barcelona to Porto
| Airline | Type | Notes |
|---|---|---|
| Ryanair | Direct, low-cost | Usually the cheapest base fares; flies into Porto several times weekly from T2. Watch baggage fees. |
| Vueling | Direct, low-cost | Frequents from T1 with better schedule spread across the day. |
| TAP Air Portugal | Direct / via Lisbon | Competitive on some dates and useful if you’re crediting miles or want a full-service option. |
On most dates Ryanair and Vueling undercut each other, so always compare both before booking.
Best time to fly Barcelona to Porto
Porto is a year-round destination with an Atlantic climate, so price should drive your timing more than weather:
- Cheapest: January, February and November. Cool and occasionally rainy, but the port cellars, Livraria Lello and the Ribeira are all open and hotel rates drop with the fares.
- Mid-range: March–May and October. Pleasant temperatures, fewer crowds and fair prices — arguably the best overall value.
- Most expensive: June–September and São João (late June), when the city fills up. Book two to three months ahead for summer.
Money-saving tips for this route
- Compare Ryanair and Vueling on every date. The cheapest carrier changes week to week.
- Pack hand luggage only. A cabin bag under the seat is cheap or free; a checked bag can double a €35 fare.
- Take the first flight of the day. Early departures are the cheapest slots and land you in Porto before noon.
- Book two one-ways instead of a return. Mixing carriers (out with one, back with another) frequently beats any round-trip fare.
- Go Sunday-to-Thursday. A weekday-based trip is often €40+ cheaper per person than a long weekend.
