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 such as EWR-LAS and the first Boeing 737-800 retrofit. However, there are no direct observations or confirmed Starlink flights on the SFO-BOS route, and regional fleet rollout is mostly complete but does not guarantee mainline route coverage. Given the lack of route-specific observations and the fleet coverage slightly above 50%, the probability is anchored at the fleet coverage ratio (0.522) without upward adjustment, reflecting moderate likelihood but uncertainty on this specific route.
