Aircraft load factors are used to measure aircraft in-flight capacity utilization.
|Domestic Revenue Load Factors (percent)||Aug-00||Aug-01|
|Passenger revenue load factor||75.55||75.78|
|Passenger revenue load factor change from same month previous year||2.10||0.23|
|Overall aircraft revenue load factor||60.22||58.86|
|Overall aircraft revenue change from same month previous year||0.96||-1.36|
|Freight revenue load factor||34.22||30.80|
|Freight revenue load factor change from same month previous year||0.07||-3.43|
NOTES: The current value is compared to the value from the same period in the previous year to account for seasonality.
Load factor relates 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 do not include international flights by U.S. domestic carriers or domestic flights by foreign carriers.
