The Terminal Area of Adolfo Suárez Madrid-Barajas Airport is made up of two separate buildings: Terminal T4 (Main Building) and Terminal T4S (Satellite Building). They are connected by a high-frequency automated train. Depending on the origin and destination of your flight, you will either have to change terminals or wait for your connection in the same building.
There are also train, bus or microbus services linking T4 and T4S with terminals T1, T2, and T3.
Check all the information on our connections page at Madrid airport or at other international airports.
