In 2026, the most popular way to get from Madrid-Barajas Airport (MAD) to the city center is the Exprés Aeropuerto (Airport Express) bus. The fare is a flat rate of €5 ($5.50). These bright yellow buses run 24 hours a day, 365 days a year, with a frequency of every 15–20 minutes during the day and every 35 minutes at night. The journey to the central Atocha train station takes about 40 minutes. You can pay via contactless credit card, mobile phone, or cash (though only small bills are accepted). Alternatively, the Cercanías (commuter train) costs roughly €2.60, and the Metro costs about €5.00 (including the mandatory "Airport Surcharge"). In 2026, the Airport Express bus remains the preferred "shuttle" for many tourists because it has dedicated luggage racks and drops passengers at major hubs like Plaza de Cibeles and Atocha, offering a more scenic and comfortable "point-to-point" experience than the subterranean metro for a very reasonable price.
