Officially called Adolfo Suárez Madrid–Barajas Airport (MAD) but more commonly known as Madrid Barajas Airport, this is the main airport serving the Spanish capital of Madrid. Size-wise, Madrid Airport is the second largest in Europe after France’s Paris Charles de Gaulle Airport (CDG). Before the COVID-19 pandemic, Madrid Airport handled 61.8 million passengers, making it the busiest airport in Spain and the 22nd busiest globally.
More recently, Spanish airport operator Aena announced that it wants to expand Madrid Airport’s capacity to handle 80 million passengers a year. To achieve this, they have allocated 750 million euros to bridge the gaps between terminal T1, T2, T3, and the much newer Terminal 4. The project is expected to be finished in 2026.
