World's Busiest Airports Dataset: Passenger Traffic, Rankings & History (1932–2026)

World's Busiest Airports Dataset is a curated, source-linked collection of global airport traffic rankings and historical title data. It includes final 2025 top-10 rankings for total passenger traffic, international passenger traffic, cargo traffic and aircraft movements; a documented history of the world's No. 1 passenger airport from 1932–2025; and a separately labelled preliminary H1 2026 international passenger update. Final 2025 data is kept separate from preliminary H1 2026 data so unlike periods are not mixed. Research article: What Is the Busiest Airport in the World?
