High Quality Content by WIKIPEDIA articles! Berlin Tegel "Otto Lilienthal" Airport (IATA: TXL, ICAO: EDDT) is the main international airport in Berlin, Germany. It lies in Tegel, a section of the northern borough of Reinickendorf, 8 km (5.0 mi) northwest of the city centre of Berlin. Tegel Airport is notable for its hexagonal terminal building around an open square, which makes for walking distances as short as 30 m (98 ft) from the aircraft to the terminal exit. In 2010, the airport served just over 15 million passengers, making it by far the biggest airport serving Berlin and the fourth busiest airport in Germany. The airport is scheduled to close by 3 June 2012, the day the new Berlin Brandenburg Airport is set to become operational.
