United Airlines has an installed rollout status with a fleet coverage of 51.9%, which sets a minimum probability floor of 0.519 for all routes, including TYS->IAD. Although there are zero direct observations on this route, the fleet coverage and multiple high-confidence news reports about United's Starlink installations on over 300 regional aircraft and recent mainline flights with Starlink strongly support a probability above 0.50. Given the lack of route-specific observations, the probability is anchored slightly above the fleet ratio to 0.52, reflecting the medium confidence from news and community sightings but conservative due to no direct route data.
