Eight air travel statistics worth knowing
Airline and airport totals are not interchangeable. Airline statistics count passengers carried on scheduled services, while airport totals describe passenger movements through airports. This page keeps those measures separate so each number can be used in the right context.

A quick note on the measures
Passengers carried
ICAO's scheduled-service total describes airline passengers. It is useful for understanding the scale of airline travel worldwide.
Airport passenger movements
ACI's airport total is a measure of traffic through airports. It is useful for understanding airport activity and is not a like-for-like substitute for airline passengers carried.
Passenger-kilometers
This measure combines people and distance traveled, so it helps show changes in total travel demand beyond a simple passenger count.
