United Airlines has a very high fleet coverage ratio of 95.6% with Starlink fully deployed, which sets a strong floor for the probability. Although there are zero direct observations on the GSO->IAD route, the airline's rollout status is fully deployed and recent news confirms active Starlink use on mainline flights, including inaugural flights and media tests. Community sightings confirm completion of regional fleet rollout. Given the critical scoring rule for fully deployed airlines with fleet coverage above 50%, the probability cannot be scored below the fleet ratio despite zero observations. The lack of route-specific observations is likely due to incomplete flight tracking data rather than absence of Starlink. Therefore, the probability is anchored at the fleet coverage ratio of 0.956 with high confidence.
