Warsaw Chopin Airport (Polish: Lotnisko Chopina w Warszawie Polish pronunciation: [lɔtˈɲiskɔ ʂɔpɛna v var'ʂavʲɛ]) (IATA: WAW, ICAO: EPWA) is an international airport located in the Włochy district of Warsaw, Poland. As Poland's largest, covering 834 hectares (2,060 acres) of land, and busiest airport, Warsaw Chopin handles just under 40% of the country's air passenger traffic. Warsaw Chopin handles approximately 300 scheduled flights daily and an ever-rising number of charters. London, Chicago, Frankfurt, Paris, and Amsterdam are the busiest international connections, while Kraków, Wrocław, and Gdańsk are the most-popular domestic ones. Formerly known as Warsaw-Okecie Airport (Port lotniczy Warszawa-Okęcie) or Okecie International Airport, the airport bore the name of its Okęcie neighborhood throughout its history, until its renaming for Polish composer and former Warsaw resident Frédéric (Fryderyk) Chopin in 2001. Despite the official change, "Okecie" ("Lotnisko Okęcie") remains in popular and industry use, including air traffic and aerodrome references. An underground railway station connected from the airport to Warsaw's suburban rail system was opened in June 2012 in time for the Euro 2012 football championships and on 25 November 2013, the airport announced accommodating – for the first time in history – its 10 millionth passenger in a single year. The second international airport of the city is the much smaller Warsaw Modlin Airport, which opened in 2012 and is used for low-cost traffic.
