United Airlines has a fleet coverage ratio of 36.7% with Starlink installed, and rollout status is 'installed'. Although there are zero confirmed Starlink observations on the IAD->SDF route, the critical scoring rule for 'installed' status with fleet ratio below 0.50 sets the fleet ratio as a floor, not a ceiling. Recent news confirms active Starlink deployment on United's mainline and regional fleets, including media flights and inaugural routes, supporting the presence of Starlink on many aircraft. Community sightings confirm rollout completion on regional US routes, which likely includes IAD->SDF. Given zero direct observations but strong fleet and news evidence, the probability is anchored at the fleet ratio floor of 0.367, rounded to 0.37, with a 'likely' confidence tier and medium confidence in estimate.
