Berlin-Tegel International Airport "Otto Lilienthal" (ICAO: EDDT) is situated in Tegel, a section of the northern borough of Reinickendorf. Tegel is referred to as the "Frequent Flyer Airport" and has the most scheduled flights of the three airports serving Berlin. In 2006, it served 11.8 million passengers. The airport is scheduled to close in 2011, six months after the formation of a new terminal expansion and the renaming of the Berlin-Schoenefeld International Airport to the Berlin-Brandenburg International Airport (BBI), which is slated to handle all Berlin flights thenceforth.

During the Berlin Airlift in 1948, the longest runway in Europe (2,400 m) was built at Tegel. Modern facilities were built in the 1970s, and Tegel began to replace Tempelhof International Airport as the main airport of West Berlin. During the Cold War, because of the special status of West Berlin, air traffic was restricted to Allied airlines (particularly Air France, Pan American World Airways, Trans World Airlines, and British Airways).

Tegel Airport is notable for its hexagonal terminal building around an open square, which makes for walking distances as short as 100 ft. from any airplane, through luggage and customs, to taxi, bus or car-parking.
