Barcelona's main airport, known as Josep Tarradellas Barcelona-El Prat Airport, serves as the key international air hub for the city. Situated in the municipalities of El Prat de Llobregat, Viladecans, and Sant Boi, it's the most significant airport in Catalonia and ranks as Spain's second-largest and busiest airport. As one of Europe’s major portals for leisure travel, it recently ranked as the sixth-busiest airport on the continent.
In 2019, Barcelona Airport saw passenger numbers exceeding 52 million before the pandemic affected global air travel. However, by 2024, statistics from Statista indicate the airport had surpassed pre-pandemic figures, serving over 55 million passengers. Much of this growth has been driven by low-cost carriers.
Low-cost airlines like Level and Vueling have significant hubs at the airport, with Air Europa, Iberia, easyJet, and Ryanair also maintaining a strong presence. Despite the popularity of a new high-speed rail line connecting Barcelona to Madrid, domestic flights remain a substantial component of the airport's operations. "The air route between Barcelona and Madrid Barajas Airport (MAD), which remains the most important route served by the airport, was once the busiest air route globally."
