KEY: R = revised.

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

NOTES

Aircraft-kilometers 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-kilometers 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-kilometers to Available seat-kilometers.

Heat equivalent factor used for conversion is 37,626.7 Kilojoules/liter.

1.609344 kilometers = 1 mile.

3.785412 litres = 1 gallon.
