DIRECTIONAL ORIGIN AND DESTINATION FILE (DOMESTIC) (DATA BANK 2C), 1968 TO PRESENT. NARS/DF-73-011
The file contains domestic outbound and inbound air passenger totals for the quarter of the file date and the three immediately preceding quarters, for domestic routings which have been classified as unidirectional by applying trip breaking criteria to all ticketed routings. The same passenger data for domestic portions of international routings is stored in separate fields as well as being included in the totals mentioned above. All downline points in the directional routing are identified. A directional routing is one in which all segments are flown in essentially the same direction, based on criteria involving direction changes and distances flown relative to direction changes. Beginning with 1972 the data are cross posted, meaning each city pair appears in the file twice, with each city as the base city once and the reference city in the other case. Source documents; the file is developed from the ticket O and D file. Information is a voluntary carrier submission. Publications; "Origin-Destination Survey of Airline Passenger Traffic (Domestic)" published by the airline finance and accounting Conference, 1709 New York Avenue, N.W., Washington, D.C. 20006.
