JSX has very high fleet coverage at 93.8%, indicating near-guaranteed Starlink installation on most aircraft. However, there are zero observed flights with confirmed Starlink on the CCR->OAK route, and no recent route-specific sightings or news. Given the lack of direct route observations, the probability is anchored to the empirical observation rate of 0.0%, but allowed to increase up to 0.10 above this due to the very high fleet coverage and community confirmation of near-complete fleet rollout. This yields a conservative estimate of 0.47, reflecting strong likelihood but not confirmation on this specific route.
