Cheap flights from Bilbao to Madrid

Madrid summers are hot and bright, winters cooler and shorter in daylight, so a midday arrival can feel different in July than in January. October is the lowest-priced month in the calendar here, and the months around it usually keep fares gentler than peak holiday periods. Weekday flights and dates away from school holidays and Christmas tend to price lower, while weekends and holiday weeks firm up. Book earlier for December and for any trip tied to a fixed event, because the cheapest seats go first on a route this short.

The first difference you feel is whether your fare buys flexibility or just a seat: some tickets include a bag, seat choice or changes, while others charge for each. Iberia, Air Europa, Air Nostrum, Portug and KLM Royal Dutch Airlines are the full-service or regional names on the list; Volotea, Vueling Airlines, Wizz Air Malta, Wizz Air UK and Air Europa express are the low-cost names, and direct flights exist alongside connecting options. Check each quote for stops, baggage and change rules before you pay, because the same route can be sold under very different conditions.

You land at Barajas, northeast of Madrid's centre, and the usual ways into town are metro, airport express bus, suburban rail or taxi. Terminals are spread out, so check which one your flight uses before you travel and allow time for transfers between them. If you arrive late, confirm that your chosen public transport still runs, and keep the address of your hotel handy for the driver.

Country facts: Wikidata

• Check whether your fare includes cabin and checked baggage, because low-cost tickets often charge for both.
• Confirm your departure is Bilbao Airport and your arrival is Barajas, not another airport serving the city.
• Look at the routing on each quote to see if it is nonstop or a connection.
• Check identity documents for a domestic Spanish flight before you leave for the airport.
• Compare October dates with your preferred month, and book earlier around school holidays and Christmas.
