As of 2014, there are five major airports in the greater Madrid area, four small and one large. The Madrid-Barajas International Airport is the largest of the five and is the main hub of Iberian Airlines, the flag air service of Spain.
The other four airports are Cuatro Vientos Airport, Torrejon Airport, Getafe Air Base and Monforte Airport. Of these, the first three are listed as regional airports, while Monforte is listed as a local airport. The Madrid-Barajas Airport features four runways, while the Cuatro Vientos and Getafe have two runways each. The Torrejon Airport has one runway. OurAirports does not provide runway information for Monforte, but the airport presumably has at least one.
