(b) Schedule T-100 shall be filed monthly as set forth in§ 298.60.

(1) Schedule T-100 collects summarized flight stage data and on-flight market data from revenue flights. All traffic statistics shall be compiled in terms of each flight stage as actually performed. The detail T-100 data shall be maintained in such a manner as to permit monthly summarization and organization into two basic groupings. The first grouping, the nonstop segment information, is to be summarized by equipment type, within class of service, within pair-of-points, without regard to individual flight number. The second grouping requires that the enplanement/deplanement information be broken out into separate units called on-flight market records, which shall be summarized by class of service, within pair-of-points, without regard for equipment type or flight number.

(2) Joint-service operations. The Department may authorize joint service operations between two direct air carriers. Examples of these joint-service operations are: blocked-space agreements; part-charter agreements; code-sharing agreements; wet-lease agreements, and similar arrangements.

(i) Joint-service operations are reported by the carrier in operational control of the flight, i.e., the carrier that uses its flight crews under its own FAA operating authority. The traffic moving under these agreements is reported on Schedule T-100 the same way as any other traffic on the aircraft.

(ii) If there are questions about reporting a joint-service operation, contact the BTS Assistant Director—Airline Information (fax no. 202 366-3383, telephone no. 202 366-4373). Joint-service operations are reported in Schedule T-100 in accordance with this paragraph (b).
