Iberia has reached the 80th anniversary of its Madrid-London route, which began in 1946 as the airline’s second international destination after Lisbon. The initial service operated from London’s Croydon Airport with two weekly flights using DC-3 aircraft that carried 21 passengers each.
Today, the route supports more than 20 daily flights combining operations by Iberia, Iberia Express, and British Airways. Iberia runs up to eight flights per direction between Madrid and London’s Heathrow Airport. Iberia Express adds two daily flights to Gatwick, while British Airways serves Heathrow and London City Airport.
For 2026, Iberia plans to offer over 1.1 million seats on the route using Airbus A320 family aircraft. The connection now functions as a high-frequency air bridge between the two capitals, reflecting its growth in capacity, frequency, and passenger volume within Iberia’s European network.
