If you've been waiting for a sign to book that spring getaway, this is it. Ryanair has just launched a massive 48-hour flash sale with one-way flights starting from just €16.99 to over 230 destinations across Europe, valid for travel in May and June 2026. Combined with the usual late-spring competition from low-cost rivals, this is one of the strongest weeks for cheap European travel we've seen this year.

Berlin → Barcelona — from €27.99 (Ryanair)

A quick note on Berlin: Ryanair is closing its Berlin base and halving capacity from winter 2026-27, so these fares may not last beyond this season. Right now, BER–BCN is bookable from around €27.99 one-way for late May travel — a smart route to lock in before schedules thin out.
