Milan–Malpensa Airport (IATA: MXP, ICAO: LIMC), formerly City of Busto Arsizio Airport, is the largest airport for the Milan metropolitan area in northern Italy. It serves 15 million inhabitants in Lombardy, Piedmont and Liguria. The airport is located 49 kilometres (30 mi) northwest of central Milan, next to the Ticino river, which is a border between Lombardy and Piedmont. The airport has two terminals and two runways. There is a dedicated cargo terminal called "CargoCity", which handles over 435,000 tons of traffic annually. The first industrial airport was opened in 1909 near the Cascina Malpensa, an old farm, by Giovanni Agusta and Gianni Caproni to test their aircraft prototypes. This airport was then opened for civil operation in 1948 during the war reconstruction period, in order to serve the northern area of Milan. In 2014, Malpensa Airport handled 18,851,238 passengers, up 5% on 2013; it is currently the 28th busiest airport in Europe in terms of passengers. Until 2008, Malpensa Airport was a major hub for Alitalia. As of early 2015, Malpensa, together with Rome Fiumicino Airport, remains the top Italian airport in terms of international passenger traffic, and the leading for freight and cargo.
