KEY: Btu = British thermal unit; R = revised.

a U.S. owned carriers only. Operations of foreign-owned carriers in or out of the United States not included.

NOTES

Aircraft-miles include all four large certificated 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 include all four large certificated 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.

Load factor: Ratio of Passenger-miles to Available seat-miles.

Heat equivalent factor used for Btu conversion is 135,000 Btu/gallon.
