World’s Largest Air Passenger and Freight Traffic by
Measuring the importance of a metropolitan area in the
global air transport system by using the
freight traffic of its
largest airport can be misleading. This is particularly the case
for large metropolitan areas that have more than one airport,
implying a distribution of the traffic. For instance, while it
is Atlanta that has the largest passenger airport in terms of
traffic, it is London and New York, with 3 major airports each,
that account for the largest amount of air traffic handled by
the metropolitan area. However, freight activity shows little
difference, implying that unlike passenger traffic, freight
activity is usually concentrated in a single airport.
