Aircraft load factors are used to measure aircraft in-flight capacity utilization.
|Revenue Load Factors (percent)||Jul-00||Jul-01|
|Passenger revenue load factor||76.21||75.31|
|Passenger revenue load factor change from same month previous year||0.12||-0.90|
|Overall aircraft revenue load factor||60.82||58.51|
|Overall aircraft revenue change from same month previous year||-0.41||-2.31|
|Freight revenue load factor||32.25||27.55|
|Freight revenue load factor change from same month previous year||-1.85||-4.70|
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.
