Lufthansa's headquarters are located in Cologne (Köln), but its primary operational base and global hub is in Frankfurt am Main for several historical and logistical reasons. After World War II, when Lufthansa resumed operations in 1955, the airline was unable to use its traditional home of Berlin because the city was divided and controlled by Allied forces (Lufthansa was not even allowed to fly into Berlin until 1990). Frankfurt was chosen as the primary hub because of its central geographic location in West Germany and its status as a major U.S. military airbase (Rhine-Main Air Base), which provided the best-developed infrastructure for international flight at the time. Furthermore, Frankfurt is the financial heart of Germany, providing a massive local market of high-value business travelers. In 2026, Frankfurt Airport (FRA) remains the "unshakable centerpiece" of Lufthansa's strategy, featuring four runways and the dedicated "Lufthansa Terminal 1" that handles over 50 million passengers annually, ensuring that while the administrative offices stay in Cologne, the "heart" of the airline's operations beats in Frankfurt.
