Airline revenue passenger-miles (RPM) are a measure of intensity of use of the air travel system. In 2008, the 740 million passengers traveling on U.S.-based airlines collectively traveled 806 billion miles. On average, a passenger traveling domestically traveled 872 miles. An international passenger traveling on a U.S.-based airline traveled an average of 2,674 miles to the first destination outside the U.S.

In 2008, airlines operating in the United States had 79.5 percent of their available seat-miles (ASM) occupied by passengers. Capacity utilization for domestic carriers was very similar for domestic and international segments, with 79.8 percent of ASM occupied for domestic flights, and 79.0 percent of ASM occupied for international flights. Foreign airlines that originated flights in the U.S. had a load factor of 76.0 percent.
