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 with 55 daily flights in 2012. The schedule has been reduced since the February 2008 opening of the Madrid–Barcelona high-speed rail line which covers the distance in hours. Subsequently, the route has been overtaken by London-Dublin and Paris-Toulouse. In 2007, the airport processed more than 52 million passengers. Barajas was voted "Best Airport" in the 2008 "Condé Nast Traveller Reader Awards". 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. On 27 January 2012, Spanair suspended all flights affecting Madrid–Barajas as well as other domestic and international connections. 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 that the airport would be renamed "Aeropuerto Adolfo Suárez, Madrid–Barajas".
