United Airlines has a fully deployed Starlink rollout with 95.6% fleet coverage, which sets a strong baseline probability for all routes including IAD->TYS. Although there are zero direct observations on this route, the critical scoring rule mandates using the fleet coverage as a minimum probability for airlines with rollout_status 'fully_deployed' and fleet_ratio >= 0.50. Recent news confirms active Starlink deployment on United's mainline and regional fleets, and community sightings verify completion of regional fleet installations. Given the high fleet coverage and corroborating evidence, the probability is anchored at 0.956 despite no route-specific observations.
