Cheap flights from San Sebastian to Prague

March is the cheapest month among the months with listed fares, and December plus the destination's summer weeks usually push prices up. The months with prices run from October through July but skip April, August and September, so the calendar is uneven rather than a full year. Weekday departures are often cheaper than weekend ones, and school holidays, Christmas and the destination's summer add pressure to the same dates. Check the dated fares before you settle on a month, because a cheaper fare can disappear while you compare connections.

Iberia is the full-service carrier most travellers start comparing, followed by BA CityFlyer, Volotea and Vueling Airlines. None of the listed options is direct, so every itinerary connects and the transfer airport matters as much as the fare. Volotea and Vueling Airlines are low-cost, which can mean a lower base price but extra charges for bags, seats or changes; Iberia and BA CityFlyer usually include more in the ticket. Check baggage, seat selection and change rules on the exact fare you choose, because the same route can be priced very differently.

The transfer from Ruzyne into Prague is the first real task after landing, so allow for it in your plans and check how late public transport or taxis run if you arrive at night. The airport sits outside the city centre, and the journey in is by road or public transport rather than a short walk. Choose accommodation with the arrival time in mind, because a late landing can make the first hour slower and more expensive to manage. Once you are in the centre, Prague is compact, but the airport side of the trip is not.

Country facts: Wikidata

• Check what each fare includes, because low-cost options can add baggage, seat and change fees on top of the base price.
• Confirm the departure airport is San Sebastian, since a ticket showing another Spanish airport means a different start to the journey.
• Look at the connection time and airport, not just the total price, especially when flights are on separate tickets.
• Check entry documents for the Czech Republic before you book, not at the airport.
• Compare March with December and the summer months, because the cheapest month is not always the best fit for your dates.
• Book flexible dates if your trip touches school holidays or Christmas, since those periods tighten availability.
