Origin-Destination 40 Percent Survey of Airline Passenger Traffic
On January 19, 2021, DOT issued a Notice of Proposed Rulemaking to improve the collection of aviation traffic data in the Origin-Destination Survey of Airline Passenger Traffic (O&D). The Updates to the Origin-Destination Survey of Airline Passengers Final Rule published in the Federal Register on January 31, 2023.
A summary of the Final Rule’s changes to the existing O&D regulations include, but are not limited to:
- Changed the reporting carrier from first lifted carrier to issuing carrier
- Increased the sample size from 10 percent to 40 percent
- Added new data elements and eliminated others
- Increased the frequency of reporting from quarterly to monthly
- Reporting scheduled year and month of travel for each coupon
- Increased the number of reporting carriers (all U.S. certificated and commuter air carriers who conduct scheduled service and immunized foreign air carriers)
Compliance with the reporting provisions is required for air transportation taking place on or after July 1, 2025.
A reporting carrier means the U.S. Certificated Air Carrier or Commuter Air Carrier that is required to report O&D data and reported a given itinerary to the Department.
Which air carriers are required to report O&D data on and after July 1, 2025?

If you are: |
You must: |
|---|---|
| A U.S. certificated (14 CFR part 241) or commuter air carrier (14 CRFR part 298) conducting scheduled passenger services, excluding helicopter carriers | Participate in the Passenger O&D Survey covering domestic and international operations. The Reporting Carrier List will be published 75 days before the beginning of each reporting period. |
| A foreign air carrier granted antitrust immunity (49 U.S.C. 41308 and 41309) | Submit O&D data to the Bureau of Transportation Statistics. Foreign air carriers granted antitrust immunity under 49 U.S.C. 41308 and 41309 are not considered Reporting Carriers under 14 CFR part 241, Sec. 19-8, but do report the same data under different legal authority. |
A combination of flown lift usage, sampling process criteria, and the Category One and Category Two ticket evaluation determines if a ticket is reportable.
Flight Lift Usage is a record or indicator in the accounting system of the issuing carrier that represents a passenger ticket coupon that has been used by the passenger for travel on a flight.
Ticket means a legal contract between an Issuing Carrier and a Revenue Passenger for transportation.

*A Reporting Carrier is a carrier that appears in the published Reporting Carrier List for the applicable reporting period.
