Cheap flights from San Sebastian to Madrid

School holidays, Christmas breaks and Madrid's summer pull more people onto this route, so fares rise and fall with the calendar. October is cheapest in the dated fares, while December and the summer months sit higher. Midweek departures are often easier to price than weekend ones, and early or late flight times can help if you can handle the airport hours. Once your dates are fixed, book promptly for holiday periods, because the lower fares are limited.

Iberia, Volotea, Vueling Airlines, APG Airlines, Binter Canarias, BA CityFlyer and British Airways appear on this route, but the itinerary matters as much as the name. A direct flight is available, and other options can connect, adding a stop and waiting time to the journey. Check the flight details before you choose, because two tickets with the same carrier can differ in baggage, seat selection and change rules. Some fares are unbundled and others include more; the ticket terms show what you are actually buying.

Arriving late changes the last leg of the trip, because Barajas sits outside central Madrid and fewer public-transport options may be running. By day, metro, suburban rail and bus links connect the airport with the city, and the airport's size means you should allow time to move between areas. Check the terminal on your ticket, since Barajas has several and they are not all served the same way. If you have hold baggage, allow for reclaim before you plan onward transport.
