United Airlines has a very high fleet coverage ratio of 95.6% with Starlink fully deployed across its fleet. Although there are zero direct observations on the BOS->IAD route, the critical scoring rule mandates that for fully deployed airlines with fleet coverage above 50%, the probability cannot be scored below the fleet ratio. Recent news confirms active Starlink installations on mainline United aircraft, including inaugural flights and media tests, and community sightings confirm completion of rollout on 300+ regional aircraft. Given the high fleet coverage and strong rollout status, the probability is anchored at the fleet ratio with high confidence despite lack of route-specific observations.
