Berlin Brandenburg Airport Willy Brandt is an international airport in Schönefeld, just south of the German capital and state of Berlin. The new airport replaced Tempelhof, Schönefeld, and Tegel airports, and became the single commercial airport serving Berlin and the surrounding State of Brandenburg, an area with 6 million inhabitants. With projected annual passenger numbers of around 34 million, Berlin Brandenburg Airport has become the third busiest airport in Germany, surpassing Düsseldorf Airport.

The airport was originally planned to open in October 2011, but the project encountered a series of delays and opened for commercial traffic on 31 October 2020. Schönefeld's refurbished passenger facilities were incorporated as Terminal 5.
