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) north of the city 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 2008, the airport served over 14,530,000 passengers, making it by far the biggest airport serving Berlin. The airport is scheduled to close in 2012, six months after the completion of the new Berlin-Brandenburg International Airport that is slated to handle all commercial flights to and from Berlin. Tegel Airport serves as hub for Air Berlin, and as focus city for Lufthansa. Additionally, it is the most important base for the charter business of Germania. The two dominant operators, Air Berlin and Lufthansa, each handle around 30% of the scheduled commercial flights.
