Monthly data, not seasonally adjusted
The air mode is generally used for cargoes that are time-sensitive and high-value. BTS collects data for air freight and mail that moves on U.S. carriers' domestic and international operating entities.
|U.S. Air Carrier Cargo Revenue Ton-Miles||Dec-10||Dec-11|
|International Cargo Revenue Ton-Miles (millions)||2,178||2,106|

NOTES: The current value is compared to the value from the same period in the previous year to account for seasonality.
International data in this file cover all non-domestic operating entities of U.S. air carriers. The non-domestic operating entity categories include "Atlantic," "Latin America," "Pacific," and "International." The "International" operating entity classification covers operations for carriers that do not classify certain operations as being conducted by the other three operating entities.
Data for September 2002 and earlier are not strictly comparable to more recent data due to a change in reporting requirements. More carriers became required to report starting October 2002.
