Domestic Aircraft Revenue Load Factors (monthly data, not seasonally adjusted)

Aircraft load factors are used to measure aircraft in-flight capacity utilization.

Revenue Load Factors (percent) May-00 May-01
Passenger revenue load factor 73.01 69.71
Passenger revenue load factor change from same month previous year  3.58 -3.30
Overall aircraft revenue load factor 59.05 55.19
Overall aircraft revenue change from same month previous year  2.41 -3.87
Freight revenue load factor 34.88 30.29
Freight revenue load factor change from same month previous year  0.93 -4.59

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.
