Berlin Brandenburg Airport — Berlin, Germany

Berlin Brandenburg Airport finally opened on October 31, 2020, under the code BER, after a construction saga that stretched roughly nine years past its original target date due to repeated technical and fire-safety setbacks. Located 157 feet above sea level, BER runs two runways and replaced both of Berlin's older airports, Tegel and Schönefeld, consolidating the German capital's air traffic into a single facility for the first time in decades. Officially named Flughafen Berlin Brandenburg 'Willy Brandt' after the former chancellor, BER sits south of the city center in the state of Brandenburg, giving the airport its name even though it primarily serves Berlin. The long delay became a running joke in German media and a symbol of infrastructure struggles nationally before the terminal finally welcomed its first flights. Today BER handles the bulk of scheduled traffic in and out of the reunified capital, a role once split between the divided city's separate airports during the Cold War.
