Yes, Berlin Brandenburg Airport (BER) is fully open and has been the primary international gateway for the German capital since its official opening on October 31, 2020. While it famously suffered nearly a decade of delays and technical scandals—originally scheduled to open in 2011—those issues are now a part of history. In 2026, BER is a bustling, modern hub serving as the home base for airlines like easyJet and Lufthansa's regional operations. It features three terminals (though Terminal 2 is primarily for low-cost carriers) and is seamlessly connected to the city center via the Airport Express (FEX) and S-Bahn trains, which take about 30 minutes to reach Berlin Central Station. Despite its rocky start, the airport now processes over 20 million passengers annually. For travelers today, the biggest "delays" at BER aren't construction-related but rather the typical security wait times during peak holiday seasons, which can be mitigated by booking a free "BER Runway" security time slot online in advance.
