JSX has very high fleet coverage of 93.8% with Starlink installed on 75 of 80 aircraft, indicating near-guaranteed availability on most routes. However, there are zero observed flights with confirmed Starlink on the SNA->CCR route, and no recent news or route-specific sightings to confirm usage. Given the lack of direct route observations, the probability is anchored conservatively just above the observation ratio (0.0) but well below the fleet coverage (0.938), set at 0.38 to reflect high fleet coverage and community confirmation of near-complete fleet rollout.
