Cheap flights to Barcelona
El Prat is a Vueling base and a focus city for several low-cost carriers, which keeps fares competitive across the continent.
Low-cost carriers
Vueling, Ryanair, easyJet and Level connect Barcelona with most of Europe at fares that regularly look like typos.
The alternative airports
Girona, about ninety kilometres north, and Reus, a hundred south, serve a few ultra-low-cost routes; worth it only with the bus connection planned.
Timing the booking
Fares swing hard around trade fairs and summer weekends; moving a flight by a single day often halves the price.
