Airline revenue passenger-miles (RPM) are a measure of intensity of use of the air travel system. In 2012, the 734 million passengers traveling on U.S.-based airlines collectively traveled 818 billion miles. On average, a passenger traveling domestically traveled 886 miles. An international passenger traveling on a U.S.-based airline traveled an average of 2,705 miles to the first destination outside the U.S.

In 2012, capacity utilization for domestic carriers was 83.4 percent of available seat-miles (ASM) occupied by passengers for domestic flights, and 81.5 percent of ASM occupied for international flights. Foreign airlines that originated flights in the U.S. had a load factor of 81.8 percent.
