2. The reportable flight operations for which data must be submitted to the Department are all scheduled nonstop domestic passenger operations by a reporting air carrier to or from any reportable airport.
3. In addition to the required data for each reportable flight which must be submitted to the Department, a reporting carrier may also submit the required data for every other nonstop domestic passenger flight it holds out to the public pursuant to a published schedule.  In addition, any carrier not included in section A of this Technical Directive may voluntarily become a reporting carrier and submit Form 234 for its reportable flights for every nonstop domestic passenger flight it holds out to the public pursuant to a published schedule, provided that the BTS Assistant Director, Airline Information (AI), is advised beforehand.  Such voluntary data must be submitted for a minimum of 12 consecutive months.  The voluntary submission must 
   meet the exact reporting specifications set forth in this directive.  Volunteering carriers that wish to discontinue reporting after one year must advise the Assistant Director, AI, a minimum of 30 days before discontinuance, so that the necessary changes can be made to the Department's data programs.
4. Changes in reporting air carriers and reportable airports will be made as necessary by the Assistant Director, AI, under authority delegated in § 385.19 of the Department's regulations.
