Aircraft load factors are used to measure aircraft in-flight capacity utilization.
|Revenue Load Factors (percent)||Jun-00||Jun-01|
|Passenger revenue load factor||78.33||74.97|
|Passenger revenue load factor change from same month previous year||4.35||-3.37|
|Overall aircraft revenue load factor||62.23||58.91|
|Overall aircraft revenue change from same month previous year||2.15||-3.31|
|Freight revenue load factor||34.55||31.68|
|Freight revenue load factor change from same month previous year||-0.49||-2.87|
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.
