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.
