Cheap flights from Dublin to Barcelona

Who flies the route?

Ryanair, Aer Lingus and Vueling all fly direct from Dublin to Barcelona, with several departures most days in summer. Direct flights take around 2 hours 20 minutes. Connecting options (often via London, Amsterdam or Paris) can sometimes work out cheaper if you're flexible on time.

Best time to go

Barcelona is great year-round, but May, June and September give you warm weather without the peak-summer crowds and prices. July and August are hottest and busiest. For the cheapest fares, avoid Irish school holidays and fly midweek.

Tips for a cheap Barcelona trip

• Fly into Barcelona El Prat (BCN) — closest to the city. Some budget fares use Girona or Reus, which are 1–1.5 hours away, so check the airport.
• Midweek departures and a cabin-bag-only fare keep costs right down.
• Set flexible dates — a day either side can change the price a lot.
