In the third quarter of 2025, the U.S. Department of Transportation (DOT) transitioned to a new collection of passenger tickets, and launched the Origin-Destination Survey of Airline Passengers (OD40) program. Prior to the third quarter (Q3) of 2025, the ticket sampling collection was performed on a 10% basis.
Beginning July 1, 2025, the ticket sampling collection changed to a 40% basis of all U.S. air carriers that operate scheduled passenger service. The Domestic Average Fares in this report and data tables are based on the 40% sampling. Fares prior to Q3 2025 will remain based on the 10% ticket sampling. Find more information about the transition to the OD40 on the BTS OD-40 page.
The average U.S. domestic air fare decreased in the third quarter of 2025 to $370, down 4.7% from the second quarter 2025 inflation-adjusted fare of $388.
