Dusseldorf Airport (DUS) features a single, large integrated terminal building that is divided into three distinct concourses: A, B, and C. While some older travel guides might refer to them as "terminals," they are physically connected under one roof, allowing passengers to walk between them after passing through security. Concourse A is primarily used by Lufthansa and its Star Alliance partners; Concourse B handles most domestic and European flights (including Eurowings and Air France); and Concourse C is dedicated to non-Schengen and long-haul international flights (such as Emirates or Turkish Airlines). In 2026, the airport remains the third largest in Germany and utilizes its "all-in-one" terminal design to offer some of the fastest connection times in Europe. For travelers, this means you don't need to take a shuttle or train to move between "terminals," making the transit process significantly less stressful than at larger hubs like Frankfurt or Munich.
