Freight Traffic at the World's Largest Airports, 2010
The level of freight activity at airports tends to be different
than from that of passenger, especially in the United States. The Midwest
being the demographic and economic centroid of the United States, many air freight
forwarders have located their hubs at airports such as Memphis
(Federal Express) and Louisville (UPS) that generate little
passenger traffic. The importance of Pacific Asian airports is
linked with the specific role of the region in the global economy,
especially over electronics. Since these products tend to have a
high value-to-weight ratio, air transport is particularly suitable
for their shipping to North American and Western European markets.
Because long distance cargo planes have less range than passenger
planes, two airports play a notable intermediate role, Anchorage
(Pacific Asia - North America traffic) and Dubai (Pacific Asia -
Western Europe traffic).
