RECORD DESCRIPTION: ASQP – Mishandled Baggage Report

Sample Record Format: XX,2010,03,8004000,35000

1. ASQP – Mishandled Baggage Report (MBR) Data File

Field Description	Data Type	Length	Comments	Sample Data
Carrier code	Character	2	Two letter IATA code	XX
Year of Data	Numeric	4	Year (CCYY)	2010
Month of Data	Numeric	2	Month (MM)	03
Number of Domestic Scheduled Passengers Enplaned	Numeric	Varies		8004000
Number of Mishandled Baggage Reports (MBRs) Filed with Carrier	Numeric	Varies		35000

Number of Domestic Scheduled Passengers Enplaned: All enplaned scheduled domestic passengers are counted, both revenue and non-revenue passengers are included in this total.

Number of Mishandled Baggage Reports (MBRs) Filed with Carrier: Carriers are required to report all domestic reports of mishandled checked baggage, including delayed, lost, stolen, pilfered, and damaged baggage. Carriers must count an MBR even when the MBR does not result in a claim for compensation.

What should be reported as an MBR?

Any report filed by a passenger regarding mishandled baggage, whether or not immediately recorded by the carrier, must be reported to DOT. An MBR resolved within 30 minutes, or with the arrival of the next flight, is still reportable to DOT, and should not be filtered out. The Mishandled Baggage Report sent to DOT should include, for example, reports filed by a passenger even if the passenger had agreed to a voluntary separation from his/her baggage, courtesy tracer reports, baggage improperly checked by skycaps, baggage claimed by the wrong passenger, and baggage delayed because of security.

Even if it was determined that the carrier was not at fault, an MBR must be counted in the carrier’s submission to DOT if the passenger filed an MBR with the carrier. Also, carriers should include informal reports taken while a search was made of the carousels.

What should not be reported as an MBR to DOT?

Carriers should not include MBRs submitted for charter operations, MBRs submitted by code-share passengers that did not actually travel on a flight operated by the reporting air carrier (also, carriers must not report to DOT any MBR involving an itinerary where a code-sharing partner provides the final segment of the transportation), MBRs submitted for carry-on baggage, and MBRs submitted by international travelers even if the international traveler had a domestic leg on his or her trip, and MBRs submitted for non-domestic operations. Domestic operations encompass operations between the 50 states of the United States, the District of Columbia, the Commonwealth of Puerto Rico, the U.S. Virgin Islands and the possessions of the United States. Carriers should also exclude MBRs submitted by passengers travelling on separate tickets on different airlines, or on a single ticket for travel on different carriers that do not have a baggage transfer agreement.

1 A reporting carrier must use this form to report on-time performance data if the flight was not a codeshare flight with another U.S. carrier. A reporting carrier must also use this form to report on-time performance data if the reporting carrier operated, but did not market, a codeshare flight.

2 A reporting carrier must use this form to report on-time performance data if: (1) the flight was a codeshare flight held out to the public with only one U.S. carrier designator code (that a flight is also held out under any number of foreign carrier designator codes is irrelevant to determining whether to report); (2) the reporting carrier marketed, but did not operate, the codeshare flight; (3) there was no flight substitution; and (4) the operating carrier of the flight is not a reporting carrier.

3 A reporting carrier must use this form to report on-time performance data if: (1) the flight was a codeshare flight held out to the public with only one U.S. carrier designator code (that a flight is also held out under any number of foreign carrier designator codes is irrelevant to determining whether to report); (2) the reporting carrier marketed, but did not operate, the codeshare flight; (3) there was no flight substitution; and (4) the operating carrier of the flight is also a reporting carrier.

4 A reporting carrier must use this form to report on-time performance data if: (1) the originally scheduled flight was a codeshare flight held out to the public with only one U.S. carrier designator code (that a flight is also held out under any number of foreign carrier designator codes is irrelevant to determining whether to report); (2) there was a flight substitution (Codeshare Swap); (3) the reporting carrier marketed the originally scheduled codeshare flight but did not operate the originally scheduled codeshare flight or the substitute codeshare flight; and (4) the substitute flight was an extra section flight or the carrier that operated the flight is not a reporting carrier.

5 For the purposes of fields G, H, J, and K, a carrier must provide information as it relates to the originally scheduled flight that was not operated and subject to the Codeshare Swap and must apply that information in calculating the other fields that are based on the information in fields G, H, J, and K (i.e. M, N, O, Q, R, S). All other fields and references to them relate to the substitute flight that was actually operated.

6 A reporting carrier must use this form to report on-time performance data if: (1) the originally scheduled flight was a codeshare flight held out to the public with only one U.S. carrier designator code (that a flight is also held out under any number of foreign carrier designator codes is irrelevant to determining whether to report); (2) there was a flight substitution (Codeshare Swap); (3) the reporting carrier marketed the originally scheduled codeshare flight but did not operate the originally scheduled codeshare flight or the substitute codeshare flight; (4) the substitute flight was not an extra section flight; and (5) the substitute flight was operated by a reporting carrier.

7 For fields G and J, a carrier must provide information as it relates to the originally scheduled flight that was not operated and subject to the Codeshare Swap. All other fields relate to the substitute flight that was actually operated.
