Accounting and Reporting Directives

The Bureau of Transportation Statistics (BTS) Office of Airline Information issues periodic Accounting and Reporting Directives (A&RD) and industry letters that serve the reporting air carriers by providing clarity to the regulations. A&RD provides more specific instructions and details (e.g. aircraft type codes) about the regulations because the information was too technical or lengthy to be included due to page limitations.
