On-Time Data
OMB NO: 2138-0041
EXPIRATION DATE: 12/31/2024
Paperwork Reduction Act Burden Statement
A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of
information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control
Number for this information collection is 2138-0041. Public reporting for on-time performance is estimated to be approximately 10 hours per response for an air carrier to report
for its operations and an additional 16 hours per response if the air carrier reports for covered code-share operations, including the time for reviewing instructions, completing and
reviewing the collection of information. All responses to this collection of information are mandatory, as authorized by 14 CFR, Part 234. Send comments regarding this burden
estimate or any other aspect of this collection of information, including suggestions for reducing this burden to: Information Collection Clearance Officer, OAI/BTS/OST-R, RTS42, 1200 New Jersey Avenue, SE, Washington, D.C. 20590

carrier must also use this form to report on-time performance data if the reporting carrier operated, but did not market, a codeshare flight.

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

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.

RECORD FORMAT:
The ASQP - On Time Data reports must be created as an electronic “comma separated values” file, using ASCII
text character encoding, for uploading via the “eSubmit” application.
The comma separated values file MUST BE indicated when naming the file, by using the letters [CSV] or [csv]
following the file name, as the file name extension.
The file name is flexible and may be determined by the individual air carrier, but the comma separated values
(csv) file format is required, as outlined in the rule entitled, Submitting Airline Data via the Internet.
The fields in the sample record shown below follow the same order as the above record description, separated
by commas, and saved with the file name extension of .csv.
Suggested file name: XX201003-234ontime.csv

PART 234 – ASQP – Mishandled Baggage Report
OMB NO: 2138-0041
EXPIRATION DATE: 3/31/2019
Paperwork Reduction Act Burden Statement
A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of
information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control
Number for this information collection is 2138-0041. Public reporting for on-time performance, mishandled baggage, is estimated to be approximately 10 hours per response,
including the time for reviewing instructions, completing and reviewing the collection of information. All responses to this collection of information are mandatory, as authorized
by 14 CFR, Part 234. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to:

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 codeshare 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.
