Where this data comes from

The route data comes from the flight archive (ADS-B, adsb.lol): which connections actually flew over the last twelve full months and who flew them, combined with our own airport, runway, and airline datasets. It is reference data about observed routes - not a current timetable and no claim about bookability.

The frequency and aircraft on this page come from the flight archive (ADS-B, 12 months, October 2025 to September 2026), summarized per route per month. We do not see every flight, so it is a floor, not a count.
