JSX has very high fleet coverage at 93.8%, indicating near-guaranteed Starlink installation across its aircraft. However, there are zero direct observations on the BUR->SLC route, and no recent news or route-specific sightings to confirm usage on this route. Given the lack of route-specific data, the probability is anchored conservatively near the observation ratio (0.0) but adjusted upward due to the very high fleet coverage and community confirmation of near-complete fleet installation. The probability is set at 0.45, slightly below the fleet coverage to reflect uncertainty on this specific route.
