Cheap Flights Madrid to San Sebastián

Flights from Madrid to San Sebastián start from around $35 one way on the short hop to the Basque coast — one of Europe’s great food cities just 70 minutes from the capital. Search and book your flight to compare every Madrid–San Sebastián departure in one search.

San Sebastián packs more Michelin stars per square metre than almost anywhere on earth, plus a surf beach, a belle-époque centre and pintxos bars that need no introduction. Here is how to get there cheaply.

How to find cheap flights from Madrid to San Sebastián

San Sebastián’s airport is small and frequencies are limited, so strategy matters more here than on big routes.

Book 3–5 weeks ahead. With few daily flights, the cheap seats on each plane disappear early.
Compare the Biarritz and Bilbao alternatives. Biarritz (France, 50 km) and Bilbao (100 km) often have cheaper or better-timed flights; a flexible search prices all three.
Fly midweek and off-peak. Tuesday–Thursday departures in the low season are the route’s floor.
Consider the train seriously. The Madrid–Basque Country rail link is a genuine competitor; airlines drop fares on dates when the train runs well.

Run a flexible-date search for Madrid–San Sebastián to catch the cheap days.

Airports: Madrid and San Sebastián

Madrid Barajas Airport (MAD) is 12 km northeast of the city. Metro line 8 reaches Terminal 4 in about 20 minutes from Nuevos Ministerios, and the Cercanías C-1 train links T4 with Atocha and Chamartín. Flights to San Sebastián typically leave from Terminal 4 — but confirm, as low-cost rotations can use T1.

San Sebastián Airport (EAS) at Hondarribia is small and easy: 20 km east of the city, on the mouth of the Bidasoa river. Buses meet flights and reach the centre in 25–30 minutes. Because the airport is tiny, allow less buffer time than at a hub — 60–75 minutes before departure is plenty.

The alternatives: Bilbao (BIO) is 100 km west with frequent buses (about 70 minutes) to San Sebastián and often cheaper flights, while Biarritz (BIQ) is 50 km east with direct buses in about 50 minutes. Both are worth pricing before you book.

Money-saving tips for Madrid–San Sebastián flights

Price the Bilbao route. Flying to BIO and taking the bus can save $40+ even after the transfer, especially in summer.
Pack light. On a 70-minute flight with small aircraft, cabin-bag-only travel saves both money and time at the tiny terminal.
Book festival dates months ahead. The film festival and Semana Grande (mid-August) sell out flights and hotels alike.
Use the airport bus, not a taxi. The bus into San Sebastián is a few euros and takes under 30 minutes.
Check the train before you commit. High-speed rail to the Basque Country is comfortable, city-centre to city-centre, and sometimes wins outright.
