Flights from €19: This Week's Best European Travel Deals

From Lisbon to Rome for under €40 to Porto-Barcelona last-minute fares, here's where to find Europe's cheapest tickets this week.

Europe's low-cost carriers are heating up for shoulder season, and we've been scanning routes all week to find the best fares departing from Iberian hubs. With walkable European capitals like Rome, Madrid, Budapest, Prague, and Lisbon ranking among the world's top destinations for foot-friendly travel (according to GuruWalk's latest data), there's never been a better time to grab a cheap ticket and explore on foot. Here are the standout deals we spotted this week.

Porto → Barcelona — from around €25 one-way

Ryanair and Vueling are competing hard on this Iberian classic, with one-way fares dipping below €30 on midweek departures in late May and early June. Barcelona is one of the top 10 most walkable cities in the world, so leave the metro card at home and explore the Gothic Quarter on foot.
