Cheap flights from San Sebastian to Barcelona

Summer and the Christmas period are the expensive stretch on this route, with April the cheaper end of the year. Book outside school holidays and Friday-to-Sunday peaks if you can, and look at midweek departures for lower fares. A few weeks' lead time usually beats last-minute buying on a short domestic route, and checking the price calendar across the months shown helps you spot the dips.

The mix on this route is two low-cost carriers against one full-service airline, with nonstop service available. The budget pair usually keeps the base fare low and charges separately for hold luggage, seat choice and priority boarding, while the full-service option folds more into the ticket. Compare the total cost, not the headline price, because a basic fare plus bags can beat a bundled one.

You land at Josep Tarradellas Barcelona airport, a large airport south-west of the city, with metro, train, bus and taxi links into town. Check which terminal your flight uses before you travel, since the two terminals are not next to each other, and allow extra time if you arrive late at night when public transport thins out. If you have hold luggage, factor in the walk from baggage reclaim to the station or bus stop.
