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.
