Berlin-Tegel Airport (TXL)
Berlin?s main international airport, Berlin-Tegel has the most scheduled flights of Berlin?s two airports (in 2007, it served over 13,350,000 passengers). Located in the northern borough of Reinickendorf, it is notable for its hexagonal terminal building around an open square, which makes for walking distances as short as 30 meters from the aircraft to the terminal exit.
