Map - Berlin Tegel Airport (Berlin Tegel Airport)

Berlin Tegel "Otto Lilienthal" Airport (Flughafen Berlin-Tegel „Otto Lilienthal“) was the former primary international airport of Berlin, the federal capital of Germany. The airport was named after aviation pioneer Otto Lilienthal and was the fourth busiest airport in Germany, with over 24 million passengers in 2019. In 2016, Tegel handled over 60% of all airline passenger traffic in Berlin. The airport served as a base for Eurowings, Ryanair as well as easyJet. It featured flights to several European metropolitan and leisure destinations as well as some intercontinental routes. It was situated in Tegel, a section of the northern borough of Reinickendorf, 8 km northwest of the city centre of Berlin. Tegel Airport was notable for its hexagonal main terminal building around an open square, which made walking distances as short as 30 m from the aircraft to the terminal exit.

TXL saw its last flight on 8 November 2020 after all traffic had been transferred gradually to the new Berlin Brandenburg Airport until that date. It was legally decommissioned as an airfield after a mandatory transitional period on 4 May 2021. All government flights were also relocated to the new airport with the exception of helicopter operations which will stay at a separate area on the northern side of Tegel Airport until 2029.

The airport's grounds are due to be redeveloped into a new city quarter dedicated to scientific and industrial research named Urban Tech Republic which is to retain the airport's main building and tower as a repurposed landmark.
