Understanding Airport Traffic Metrics

Before delving into the specifics of the busiest airports, it’s essential to understand the metrics used to determine their rankings:

  • Passenger Traffic: The total number of passengers passing through an airport within a given timeframe, typically annually. This includes both arriving and departing passengers.

  • Aircraft Movements: The total number of takeoffs and landings. High aircraft movements indicate significant operational activity, essential for hub airports facilitating numerous connections.

  • Cargo Throughput: The volume of cargo handled, usually measured in metric tonnes. Some airports specialize in cargo transport, contributing to their overall busyness.

Different organizations may prioritize these metrics differently. For instance, the Airports Council International (ACI) primarily uses passenger numbers for its rankings.
