The I-92 data was originally sent to the U.S. Department of Transportation (DOT) for processing and publishing. DOT through the Volpe Center in Cambridge, Massachusetts processed and published the 1975- 1994 reports. In November 1994, DOT informed NTTO (which was USTTA's Office of Research at the time) that their budget had been cut and they were terminating the I-92 program. They offered to work with us to transition the program over to us upon their completion of processing the calendar year 1994 data. In June/July 1995, most of the historical data, reports and equipment were provided to NTTO from DOT. NTTO worked with DOT to take over the entire I-92 processing and publishing function. No additional funds or staff was provided to NTTO to assume this program. NTTO through the Commerce advanced data processing and Composition offices has processed and published this data starting with the January 1995 data/report.
In 1996, NTTO implemented a major update of the airline, country, and airport (U.S. and foreign) codes. Over 230 codes were changed or added to the I-92 coding system. NTTO has been trying to keep the coding system up to date on a monthly basis before any of the I-92 data is processed. NTTO
expects the new codes and improved processing by INS's contractor has proven to provide better data to the industry. NTTO expects that industry users will report any data anomalies that occur. We will try to work with DHS to correct the problem(s).
Since July 1995, the INS contractor has been sending TI monthly files on the records processed each month. Commerce's advanced data processing center staff runs the I-92 files to produce the data and reports. A print file is sent to the Commerce Composition staff and reports are generated directly from the print file.
TI has maintained the DOT format for the printed monthly, quarterly, and annual reports entitled "U.S. International Air Travel Statistics." The reports and data are sold by NTTO.
