Cheap Flights from London to Madrid

The route from London to Madrid covers about 1,246 km (774 miles). A nonstop flight, when scheduled, usually takes around 2h 10m gate to gate, although total trip time still depends on airport queues, transfer costs, and how early you need to arrive. This is a solid medium-length European route where a cheaper connection can look tempting until you factor in the extra travel time. If you only see one-stop options on your travel dates, connections through Amsterdam or Barcelona can widen the fare mix, but total journey time often stretches to 5 to 7 hours.

For many travelers, the cheapest time to fly from London to Madrid is outside Easter, early summer, and festive long weekends. late January to March and parts of November usually give you a better chance of seeing lower fares, especially if you can depart on Tuesday or Wednesday and avoid the busiest Friday-to-Sunday patterns. Shoulder-season trips are often the sweet spot on this business-meets-leisure route: you still get a strong travel experience in Madrid, but airlines are not dealing with the same pressure they see during bank holidays, school breaks, or sold-out weekend peaks.

For this route, compare a mix of budget and full-service carriers rather than assuming one airline always wins on value.

• Vueling: often useful on Spain, Italy, and France city-pair schedules.
• easyJet: often competitive on short-haul European routes with solid schedule choice.
• Iberia: a good benchmark on Spain-linked routes and premium-economy-style schedules.
• Air Europa: worth comparing on Spain-heavy schedules and connection options.
• Ryanair: often one of the lowest headline fares if you can travel light.

Headline round-trip fares on this route often start around EUR 75 to EUR 120 in quieter periods. A more typical booking window lands closer to EUR 175 to EUR 240, while peak travel dates can push pricing toward EUR 285 to EUR 395 or higher. Fare swings usually come from holiday demand, limited low-cost inventory, and whether you want the most convenient departure bank. On short-haul Europe trips, baggage, seat selection, and airport-transfer costs can change the real total more than many travelers expect, so always compare like-for-like fares.

On this route, airport choice can save money only if the ground transfer still makes sense for your trip. Start with Heathrow Airport on the London side and Adolfo Suarez Madrid-Barajas Airport on the Madrid side, then widen the search if the fare difference is meaningful.

• Origin side: London Gatwick (LGW) for more low-cost and leisure-heavy schedules
• Origin side: London Stansted (STN) if budget carriers are your priority
• Origin side: London Luton (LTN) or London City (LCY) when convenience outweighs the lowest fare
• Destination side: Madrid is mostly a single-airport market, so better fares usually come from flexible dates, off-peak flight times, or comparing alternative departure airports on the origin side.

Madrid works well year-round thanks to big museums, late dining, strong rail links, and easy onward access to cities such as Toledo, Segovia, and Valencia. If you are still planning the rest of the trip, see our Madrid destination guide for more ideas before you book.
