Cheap flights from Warsaw to Bilbao

January is the cheapest month to fly this route, landing just after the Christmas rush when demand drops and the sales begin. Spring and early autumn are the sweet spots for weather in Bilbao, while summer brings the crowds and the highest fares as the Basque coast fills with Spanish holidaymakers. Midweek departures are usually quieter and cheaper than Friday and Sunday, when weekend trips push prices up. Watch Polish public holidays and the Easter period, plus the Spanish long weekends that send locals to the coast. Book early for summer travel and closer to the date in winter, and keep an eye on the price calendar as your dates firm up.

Low-cost carriers do most of the work here: Wizz Air and Wizz Air Malta fly the route, along with Norwegian and Norwegian International. Full-service names on the list include Scandinavian Airlines, KLM Royal Dutch Airlines, TAP Portugal, Air Europa, Austrian and Lufthansa, and these tend to come with a connection rather than a nonstop. What is included differs sharply. Low-cost fares are built around a small cabin bag with everything else added at checkout, while full-service tickets often bundle more, and a connection sold on one ticket protects you if a leg is delayed. Book separate tickets and the risk of a missed connection is yours.

Bilbao has a single airport, and it sits close to the city, so the transfer is short whichever way you go. A taxi gets you into the centre quickly, a bus links the terminal with the middle of town, and car hire desks are there if you are heading on along the coast or inland. The terminal is compact and easy to navigate. Late arrivals are worth planning for, since the last buses run before the final flights of the day land, and rental desks keep limited hours. If someone is meeting you, agree on a spot in arrivals before you land.

Country facts: Wikidata

• Check whether your flight leaves from F. Chopin or Modlin, because Warsaw's two airports sit on opposite sides of the city.
• Look at what your fare includes before you pay, since cabin bag limits and checked baggage rules differ between the carriers on this route.
• If you are connecting on separate tickets, leave a generous gap between flights, because no one protects you when the first one runs late.
• Make sure your passport and any entry documents for Spain are in order well before departure.
• Weigh the season against your plans, as winter fares are lowest and summer travel on this route costs the most.
• Decide whether a nonstop is worth it to you against a cheaper connection through a hub.
