How to read these numbers
2025 BTS reporting-carrier domestic flights; coverage excludes carriers/flights outside the reporting program. An airport is the departure origin. Cancellation rate uses all scheduled reported flights; departure-delay rate uses flights with a known departure delay. Mean signed delays include early departures/arrivals and exclude unavailable delay records. Winter pools January, February and December of 2025. Reporting-carrier identity may differ from the marketing airline. Six-hour bins use scheduled local departure time, not actual departure time. Historical aggregates are not a flight forecast.
Map colors span the minimum and maximum available values in your current filters. Point maps locate reference points and do not shade geographic boundaries. Nearby ordering uses straight-line point distance, not a travel route. Public links preserve statistical filters and place identifiers; calculation amounts and search text stay out of the URL.
