KEY: N = data do not exist; R = revised; U = data are not available.

a Some totals include data not in the table; thus totals may not equal sum of table data.

b Includes scheduled and nonscheduled (charter) operators. By Sec. 2 of the Airline Deregulation Act of 1978 "charter air carrier" and "charter air transportation" replaced supplemental air carriers and supplemental air transportation, which were formerly Sec. 101(36) and (37) of the Act. The 24 pre-deregulation supplemental carriers now have scheduled service authority.

c Total includes only those carriers who have reported employment statistics to BTS' Office of Airline Information.

d Passenger travel totals do not include Canada because the source does not record departures and arrivals to and from Canada.

e Total Revenue Ton-Miles includes passenger, freight, express, and mail.

NOTES

Domestic encompasses operations within and between the 50 states of the United States, the District of Columbia, Puerto Rico, and the Virgin Islands. It also encompasses Canadian and Mexican transborder operations (U.S. airlines only). All other operations are considered international.
