NOTES: The current value
is compared to the value from the same period in the previous year to account
for seasonality.
Load factor is related to the potential capacity of a system
relative to its actual performance. In order to combine passenger and freight
to calculate overall aircraft load factors, a common metric is needed:
ton-miles. Thus, it is assumed that a passenger plus baggage weighs 200
pounds. The data include both transborder and foreign flights by large U.S.
carriers, but do not include any flights by foreign carriers.
The dramatic changes in the September 2001 data reflect the
impact of the terrorist attacks on Sept. 11, 2001, on aviation, including
several days in which commercial air operations were suspended.
The data reported here excludes small-certificated and commuter
carriers that began reporting T100 data in 2002 for comparability with
previous issues.
