Why is Frankfurt the busiest airport?

But rather than just catering to holiday makers, Frankfurt is a major logistical hub. Most of its passengers are business travelers and more than half of all passengers are there to transfer between flights. It handles more than 2 million tons of cargo each year, as well as 100 million animals.



Frankfurt Airport (FRA) is consistently one of the busiest in the world and the busiest in Germany due to its role as the primary global hub for Lufthansa and the Star Alliance. Geographically, Frankfurt is located in the heart of Europe, making it the perfect "intermodal" crossroads for flights connecting the Americas to Asia and Africa. In 2026, its massive volume is also driven by its CargoCity, which handles more air freight than almost any other European airport, supporting Germany's status as a top global exporter. The airport is uniquely connected to a high-speed rail station (the Fernbahnhof), allowing millions of passengers from across Germany and neighboring countries to "connect" to long-haul flights via train rather than a short-hop flight. This "seamless" integration of rail and air makes it a massive logistics engine. Additionally, Frankfurt is the financial capital of continental Europe, ensuring a constant stream of high-value business travelers who keep the airport operating at near-maximum capacity throughout the work week.
