Which Airlines Fly London to Madrid

Budget carriers: Ryanair and easyJet operate the most frequent, cheapest options, typically departing from London Stansted, Luton, or Gatwick. Expect basic fares with paid add-ons for checked bags and seat selection.

Full-service carriers: British Airways (Heathrow) and Iberia (Heathrow) offer more frequent schedules, included baggage, and better flexibility for changes — worth the premium for business travel or if your dates aren't fixed.

Which London Airport Should You Fly From?

Heathrow (LHR): British Airways and Iberia, best for connections and full-service comfort.

Gatwick (LGW): easyJet and British Airways both operate here — often a good middle ground on price and convenience.

Stansted (STN) and Luton (LTN): Ryanair's and easyJet's cheapest fares, but factor in the extra transit time and cost getting into central London.

Best Time to Book

Aim to book 5–8 weeks before departure for the best fare-to-flexibility balance on this route. Because it's a leisure-heavy corridor, prices spike hard around Easter week, the July–August summer peak, and the days around Christmas and New Year — book those windows 3+ months out if possible.

How to Find the Cheapest Fare

1. Compare budget and full-service side by side. A Ryanair fare plus a checked bag and seat selection can end up close to a British Airways fare with everything included.

2. Check both Gatwick and Heathrow departures. Price differences between the two on the same day are common.

3. Fly midweek. Tuesday and Wednesday departures run 10–20% cheaper than Friday or Sunday on this route.

4. Set a price alert rather than checking daily. See our flight price alerts guide for tools that work well on short-haul European routes.
