United Airlines is actively rolling out Starlink with about 52.2% fleet coverage, supported by multiple high-confidence news reports confirming operational Starlink flights on other routes such as EWR-LAS and the first Boeing 737-800 retrofit. However, there are no direct observations or confirmed Starlink flights on the IAD-SLC route, and no community sightings specific to this route. Given the fleet coverage and rollout status, the probability is anchored at the fleet coverage ratio of 0.522, with no observation data to suggest a lower rate. The probability is therefore set at 0.52, reflecting the fleet coverage without exceeding it, and the confidence is medium due to lack of route-specific observations.
