Sources & methodology
Each source has a defined role. Airport coordinates are not timetable data, and traffic evidence is not treated as proof of a current nonstop service.
OurAirports
Airport names, IATA/ICAO identifiers and geographic coordinates used by the airport layer. Source documentation ↗
Named sourceUS BTS
Domestic nonstop flight records from the US BTS reporting-carrier on-time dataset, imported only after an administrator uploads a verified CSV. Official source ↗
Official evidenceCalculation model
Haversine great-circle distance using a mean Earth radius of 6,371.0088 km, then an 805 km/h cruise assumption plus 30 minutes. This is our published planning model, not an external schedule.

Matched BTS route records
Evidence hierarchy
Reviewed route record: may provide a route-specific duration range and source URL.
BTS route evidence: may establish that domestic nonstop flights were recorded for the airport/destination pair in the stated reporting period.
Calculated estimate: provides a reproducible answer when no reviewed duration is available.
Source review policy
External reference data and route evidence are reviewed periodically. When route-specific evidence has a reporting or review date, that context is shown with the evidence itself.
Source changes do not automatically convert traffic evidence into a current timetable claim.
