Public access to international data of U.S. and foreign air carriers is restricted for a period of six months from the data date, except that U.S. carriers foreign-to-foreign airport data are restricted for three years.

2. Passenger Origin-Destination (O&D) Survey. Domestic data are unrestricted. International data (O&D data banks DB1A and DB2A) are permanently restricted; however, an application for restricted access to these data may be filed. (See below for more information.)

3. Domestic and International ER-586 (Service Segment Data) and Nonstop Market Report (Schedule T-9) data are unrestricted since 1997, although the international data were permanently restricted before that date. Collection of these data ended on January 1, 1990, when it was replaced by the T-100 data collection from U.S. air carriers.
