JSX has a very high fleet coverage of 93.8%, indicating near-guaranteed Starlink installation across its aircraft. However, there are no direct observations or route-specific sightings for the SNA->SLC route, and no recent news specific to this route. Given the lack of empirical route data, the probability is anchored conservatively below the fleet coverage ratio, set at 0.45 to reflect strong fleet-wide rollout but absence of direct route confirmation.
