The 10 Largest Airline Megahubs In 2025

Every year, a handful of megahub airports move more people than the airport systems of entire developed countries. We analyze the world’s ten busiest airports in order to capture more than just raw overall passenger figures. We look to create a snapshot of economic gravity, airline strategy, and the power that geography holds over the development of route networks. Aircraft volumes reflect local demand, connectivity, and the tug-of-war between transfer traffic and origin-and-destination flows.
