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-kilometers 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, pas
Passenger-kilometers 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 joule conversion is 37,626,700 joules/liter.
1.609344 kilometers = 1 mile.
3.785412 liters = 1 gallon.
