Finding Cheap Flights From Porto

Porto is served by Francisco Sá Carneiro Airport (OPO), a modern and efficient airport in northern Portugal.

Top routes include London (multiple airports), Paris, Brussels, Frankfurt, Milan, and Madrid. Porto also offers vital domestic links to Lisbon and the Azores, as well as a growing number of transatlantic flights to North and South America.

Porto Airport is a significant base for low-cost carriers, with Ryanair operating a large number of routes. easyJet, Transavia, and Vueling also have strong presences. The national carrier, TAP Air Portugal, maintains important hub connections through Lisbon, while other airlines like Lufthansa and Air France serve their major European hubs from OPO.

To find cheap flights from Porto, book European routes at least 2-3 months in advance, especially for summer travel. Sign up for low-cost airline newsletters to receive alerts for flash sales. Flying on less popular days like Tuesday, Wednesday, or Saturday consistently yields lower fares. For trips beyond Europe, compare prices for flying directly from Porto versus connecting through a larger hub like Lisbon or Madrid, as sometimes a short connecting flight can lead to a much better overall deal.
