United Airlines is actively rolling out Starlink with about 52.2% fleet coverage, supported by multiple high-confidence news reports confirming initial Starlink flights on specific routes like EWR-LAS and the first Boeing 737-800 retrofit. However, there are zero confirmed Starlink observations on the SUN-SFO route, and no direct sightings or news specifically mention this route. Given the fleet coverage and rollout status, the probability is anchored to the fleet coverage ratio of 52.2%, with no upward adjustment due to lack of route-specific observations. The confidence is medium due to indirect evidence and absence of direct route data.
