About these figures

Every large US airline reports each domestic flight's scheduled and actual times to the US Department of Transportation, which publishes them through the Bureau of Transportation Statistics about two months after each month ends. TripStow adds up the latest 12 months for each airline. See how TripStow measures punctuality, and the latest monthly report, US flight punctuality: July 2026.
