Adolfo Suárez Madrid–Barajas Airport

The airport was constructed in 1927, opening to national and international air traffic on 22 April 1931, although regular commercial operations began two years later. A small terminal was constructed with a capacity for 30,000 passengers a year, in addition to several hangars and the building of the Avión Club. The first regular flight was established by Lineas Aéreas Postales Españolas (LAPE) with its route to Barcelona. In the 1930s, flights started to serve some European and African destinations, the first international flights from the airport.

Originally, the flight field was a large circle bordered in white with the name of Madrid in its interior, unpaved, consisting of land covered with natural grass. It was not until the 1940s that the flight field was paved and new runways were designed. The first runway which started operation in 1944 was 1,400 metres long and 45 metres wide.[7] By the end of the decade the airport had three runways, none of which exist today. In the late 1940s, scheduled flights to Latin America and the Philippines started.

In the 1950s, the airport supported over half a million passengers, increasing to five runways and scheduled flights to New York City began. The National Terminal, currently T2, began construction in 1954 and opened later that year. In the Plan of Airports of 1957, Barajas Airport is classified as a first-class international airport. By the 1970s, large jets were landing at Barajas, and the growth of traffic mainly as a result of tourism exceeded forecasts. At the beginning of the decade, the airport reached the 1.2 million passengers, double that envisaged in the Plan of Airports of 1957.

In the 1970s, with the boom in tourism and the arrival of the Boeing 747, the airport reached 4 million passengers and began the construction of the international terminal (current T1). In 1974, Iberia, L.A.E. introduced the shuttle service between Madrid and Barcelona, a service with multiple daily frequencies and available without prior reservation.

The 1982 FIFA World Cup brought significant expansion and modernisation of the airport's two existing terminals.[7]

In the 1990s, the airport expanded further. In 1994, the first cargo terminal was constructed and the control tower was renovated. In 1997, it opened the North Dock, which is used as an exclusive terminal for Iberia's Schengen flights. In 1998, it inaugurated a new control tower, 71 m tall and then in 1999 the new South Dock opened, which implies an expansion of the international terminal. During this time, the distribution of the terminals changed: The south dock and most of the International Terminal were now called T1, the rest of the International Terminal and Domestic Terminal were now called T2 and the north dock was called T3.

In November 1998, the new runway 18R-36L started operations (replacing the previous 18–36), 4,400 m long, one of the largest in Europe under expansion plans called Major Barajas. In 2000, it began the construction of new terminals T4 and its satellite, T4S, designed by architects Antonio Lamela, Richard Rogers and Luis Vidal. Two parallel runways to the existing ones were also built.

The new terminals and runways were completed in 2004, but administrative delays and equipment, as well as the controversy over the redeployment of terminals, delayed service until 5 February 2006.

Terminal 4, designed by Antonio Lamela, Richard Rogers and Luis Vidal, (winning team of the 2006 Stirling Prize) and TPS Engineers, (winning team of the 2006 IStructE Award for Commercial Structures)[8] was built by Ferrovial[9] and inaugurated on 5 February 2006. Terminal 4 is one of the world's largest airport terminals in terms of area, with 760,000 square meters (8,180,572 square feet) in separate landside and airside structures. It consists of a main building, T4 (470,000 m²) and a satellite building, T4S (290,000 m²), which are approximately 2.5 km apart. The new Terminal 4 is designed to give passengers a stress-free start to their journey. This is managed through careful use of illumination, with glass panes instead of walls and numerous skylights which allow natural light into the structure. With this new addition, Barajas is designed to handle 70 million passengers annually.

During the construction of Terminal 4, two more runways (15L/33R and 18L/36R) were constructed to aid in the flow of air traffic arriving and departing from Barajas. These runways were officially inaugurated on 5 February 2006 (together with the terminals), but had already been used on several occasions beforehand to test flight and air traffic manoeuvres. Thus, Barajas came to have four runways: two on a north–south axis and parallel to each other (separated by 1.8 km) and two on a northwest–southeast axis (and separated by 2.5 km). This allowed simultaneous takeoffs and landings into the airport, allowing 120 operations an hour (one takeoff or landing every 30 seconds).

Terminals 1, 2 and 3 are adjacent terminals that are home to SkyTeam and Star Alliance airlines. Terminal 4 is home to Iberia, its franchise Air Nostrum and all Oneworld partner airlines. Gate numbers are continuous in terminals 1, 2 and 3 (A1 to E89), but are separately numbered in terminal 4 (H, J, K and M, R, S, U in satellite building).

The Madrid–Barcelona air shuttle service, known as the "Puente Aéreo" (in Spanish), literally called "Air Bridge", used to be the busiest route between two EU airports[10] with 55 daily flights in 2012.[11] The schedule has been reduced since the February 2008 opening of the Madrid–Barcelona high-speed rail line which covers the distance in ​2 ¹⁄₂ hours. Subsequently, the route has been overtaken by London-Dublin and Paris-Toulouse.

• On the morning of 30 December 2006, an explosion took place in the carpark building module D attached to Terminal 4. Authorities received a bomb threat at approximately 8:15 local time (7:15 GMT), with the caller stating that a car bomb carried with 800 kg of explosive would explode at 9:00 local time (8:00 GMT).[12] After receiving the warning, police were able to evacuate part of the airport.[13] Later, an anonymous caller stated that ETA claims responsibility for the bombing.[14] As a result of the explosion, two Ecuadorians who were sleeping in their cars died. The whole module D of the car park was levelled creating around 40,000 tonnes of debris. It took workers six days to recover the body of the second victim from the rubble.

In 2007, the airport processed more than 52 million passengers. Barajas was voted "Best Airport" in the 2008 Condé Nast Traveller Reader Awards.[15]

In December 2010, the Spanish government announced plans to tender Madrid–Barajas airport to companies in the private sector for a period of up to 40 years.[16]

On 27 January 2012, Spanair suspended all flights affecting Madrid–Barajas as well as other domestic and international connections.[17] On 20 September 2012, both runways 15/33 were renamed as 14R/32L (the longest) and 14L/32R (the shortest).

On 1 August 2015, the first scheduled Airbus A380 flight landed in Madrid-Barajas in a daily service to Dubai by Emirates.

Following the death of former Spanish Prime Minister, Adolfo Suárez, in 2014, the Spanish Ministry of Public Works and Transport announced[18] that the airport would be renamed Aeropuerto Adolfo Suárez, Madrid–Barajas. This renaming seeks recognition for Suárez's role as the first Prime Minister of Spain after the restoration of democracy and his key participation in the transition to democracy after the dictatorship of Francisco Franco.

In late 2018 and early 2019, Iberia renovated its two lounges in Terminal 4, the Dali and Velazquez lounges.

In December 2019, the airport's operator Aena announced plans to significantly expand and renovate the existing installations, increasing their yearly capacity from 70 to 80 million passengers and bridging the architectural gap between the original Terminals 1, 2 and 3 and the newer Terminal 4. The project has a budget of 750 million Euro and is set to be executed in the period from 2022 to 2026.[19]

As of December 2020, the following airlines serve 193 regular scheduled and charter routes to and from Madrid:[20]

All terminals have clearly signed taxi ranks outside the arrivals area. Official taxis are white with a red stripe and have the Madrid City Council coat-of-arms on their doors.

The Madrid Metro Line connects the airport with city centre station Nuevos Ministerios in Madrid's financial district. The Barajas Line 8 provides a fast route from the underground stations at Terminal 2 (access to T1 and T3) and Terminal 4 into central Madrid. The metro also provides links to stations on the Spanish railway network.

In October 2006, a bid was launched for the construction of a Cercanías link between Chamartín Station and Terminal 4. Now finished, this single Cercanías Line (C-1) links Madrid Barajas Terminal 4, with Chamartín Station and Atocha AVE high-speed train stations.[35] In June 2011 a decision was made to equip this link with dual gauge which will allow AVE high-speed trains to reach the airport station.[36]

The Nuevos Ministerios metro station opened a satellite check-in center in 2002[37] right by the AZCA business area in central Madrid; the satellite check-in center was permanently closed in 2006 due to security concerns.[38]

EMT (Madrid Municipal Transport Company) runs regular public bus services between the airport and Madrid (Avenida de América station): bus 200 runs as a complete line – dropping passengers at departures of terminals 1, 2 and 4 before collecting passengers in the reverse order at arrivals. The EMT public night bus service N4 (nicknamed "Buho", Owl) also services from Madrid downtown (Plaza Cibeles) to Barajas (Plaza de los Hermanos Falcó y Alvarez de Toledo, 400m from the airport through a passageway above the highway). EMT also have an express bus linking Barajas airport to Renfe's Atocha Station, the main rail station in Madrid, during day and Plaza Cibeles during night. Unlike the two services mentioned above, this line runs 24 hours of the day during all the days of the year.[39]

CRTM (Consorcio Regional de Transportes de Madrid) runs four bus services between the airport and nearby cities in the metropolitan area:

• 822: T1 - Coslada - San Fernando de Henares
• 824: T2 - Torrejón de Ardoz - Alcalá de Henares
• 827: Canillejas - T4 - Alcobendas - Universidad Autónoma de Madrid - Tres Cantos
• 828: Canillejas - T4 - Alcobendas - Universidad Autónoma de Madrid

From terminals T1 and T4 the bus company Avanzabus operates routes to Ávila, Castellón, Salamanca, Valencia y Zamora. From terminal T4 the Alsa bus company runs services to the cities of Zaragoza, Barcelona, Valladolid, León, Murcia, Alicante, Gijón, Oviedo, Lugo, Coruña, Santiago de Compostela, Burgos, Vitoria, San Sebastián, Santander, Bilbao, Logroño and Pamplona. From terminal T1 the Socibus company runs services to the major cities in Andalusia: Huelva, Córdoba, Cadiz, Jerez and Seville.

Automated People Mover that links Terminal 4 and the Terminal 4 Satellite

In early 2006, the first driverless transit system in Spain and the longest airport people mover system in Europe began transporting passengers between the new terminal (T4) and a new satellite terminal (T4S). Deploying the CITYFLO 550 automatic train control technology, the system is the only mode of transportation for passengers between the two terminals, which are spaced more than two kilometres apart.[40] Bombardier became the only contractor for the completely underground shuttle system, including the construction of the civil works, operation and maintenance of the system.

Long- and short-term car parking is provided at the airport with seven public parking areas. P1 is an outdoor car park located in front of the terminal building; P2 is an indoor car park with direct access to terminals T2 and T3. A Parking 'Express' facility, available for short periods only, is located at Terminal 2 and dedicated long-term parking is also available with 1,655 spaces; a free shuttle operates between the long-stay car park and all terminals. There are also VIP car parks.
