This directive is to remind reporting air carriers that they must submit the total number of all of mishandled baggage reports (MBRs) filed with them for scheduled domestic service. Also, the Department reissues the instructions for reporting diverted flights and rescinds Reporting Directives No. 99 and 140.
Title 14 Code of Federal Regulations Section 234.6 requires each reporting carrier to report monthly to the Department on a domestic system basis, excluding charter flights, the total number of passengers enplaned systemwide, and the total number of MBRs filed with the carrier.
The Department limited the application of the rule to large air carriers because they maintain their flight performance data in a computerized form, which makes it relatively easy for them to supply the Department with the required data. Previously in Accounting and Reporting Directives no. 99 and reiterated in Accounting and Reporting Directive no. 157, the Department instructed reporting carriers to exclude their code-share operations when calculating the number of MBRs received. At that time, the code-share relationships in existence were between large major air carriers and small regional air carriers. The code-share flights were operated by the regional carriers, which had no reporting requirement. Today, code-share relationships have grown to the point where major air carriers code share with other major carriers. These code-share relationships do not relieve the operating carrier of its reporting obligation under Section 234.6, which requires carriers to report the total number of MBRs that they receive. Reporting air carriers must report to the Department MBRs involving an itinerary where it, as a code-sharing partner, operated the final segment of the transportation. Reporting air carriers are not required to report mbrs involving an itinerary where its code-sharing partner operated the final segment of the transportation.
When reporting on-time flight statistics for diverted flights, the original scheduled flight numbers and the original scheduled origin and destination airport codes must be used. For example, an April 9 operation of Flight 1218 was scheduled to be operated from Washington, DC (DCA) to Columbus, OH (CMH); however, the flight was diverted to Cincinnati, OH (CVG) due to inclement weather in the Columbus area. Therefore, the operation of flight 1218 on April 9 should be reported as departing DCA with the actual gate-departure time and wheels-off time. However, the carrier should report zeros for the wheels-on time and gate-arrival time at CMH.
