Adolfo Suárez Madrid–Barajas Airport

Adolfo Suárez Madrid–Barajas splits into two clusters that behave almost like separate airports, and knowing which one you need is most of the battle.

Two clusters, one airport

Terminals 1, 2, and 3 sit together in the older part of the airport and share a connected building; you can walk between them. Terminal 4 and its satellite, T4S, stand on the far side of the runways — a separate structure reached by a dedicated shuttle bus or, airside, by an automated train between T4 and T4S. Iberia and its oneworld partners fly from T4, so most long-haul and a lot of European traffic departs there. Many other carriers use T1, T2, and T3.

The practical consequence: never assume T4 is a short hop from T1. If a connection or a companion’s flight crosses between the clusters, leave 45 minutes to an hour to move and re-clear security.

Getting into the city

Two rail options run from the airport, roughly 12 km northeast of the center:

• Metro Line 8 connects the terminals (stations at T1-T2-T3 and at T4) to Nuevos Ministerios in about 15-20 minutes, where you can change to the rest of the Metro. There is a small airport supplement on top of the normal fare.
• Cercanías line C-1 commuter rail runs from Terminal 4 to the main stations at Chamartín and Atocha, which is handy if you are catching onward high-speed rail or staying near those hubs.

Taxis to central Madrid run on a fixed flat fare for trips inside the city ring, which removes the usual guesswork; the ride is typically 20-30 minutes outside peak traffic.

Worth knowing

T4 is the more modern, airier building — bamboo ceilings, lots of natural light — and it is where the better lounges and dining sit. If you have a choice of connection routings, one through T4 is generally the more comfortable wait.
