KEY: Btu = British thermal unit; R = revised.
a U.S. owned carriers only. Operation of foreign-owned carriers in or out of the United States not included.
b Calculation based on unrounded figures not shown here.
NOTES
Aircraft-miles includes all four air-carrier groups (majors, nationals, large regionals, and medium regionals), scheduled and charter, passenger, and all-cargo. Fuel consumed includes majors, nationals, and large regionals, scheduled and charter, passenger, and all-cargo.
Passenger-miles includes all four air-carrier groups, scheduled and charter, passenger service only.
International operations include operations outside the United States, including those between the United States and foreign countries and the United States and its territories or possessions.
Heat equivalent factor used for Btu conversion is 135,000 Btu/gallon.
