Same journey, a different airport nearby - with an observed direct connection.
The observed direct connection between King County International Airport - Boeing Field (BFI) and Anacortes Airport (OTS) covers approximately 69 mi. The estimated flight time is around 40m. Air San Juan has been observed on this connection in the available route data.
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.
