World top 50 — total passengers (departures + arrivals)
The world's 50 busiest airports, by annual passengers — a points layer, not a choropleth: an airport is a single-site facility, not data to aggregate by country.

Circle size encodes annual passengers. The 50th spot, Zurich, sits at 29 million passengers.
Hartsfield-Jackson Atlanta (108 million passengers) has remained the world's busiest airport for over two decades, despite competition from Gulf hubs. Dubai (92 million) trails close behind, driven by its role as a connecting hub between Europe and Asia rather than domestic traffic — unlike Atlanta, whose volume comes mainly from the US domestic network.
