United Airlines has an installed rollout status with a fleet coverage of 36.7%, which sets a floor for the probability at 0.367. Although there are zero confirmed Starlink observations on the IAD->MHT route, this is likely due to incomplete flight tracking data rather than absence of Starlink. Recent high-confidence news confirms active Starlink deployment on United's mainline and regional fleets, including inaugural flights with Starlink WiFi. Community sightings also confirm rollout completion on regional US routes. Given the zero observation ratio but strong fleet coverage and news evidence, the probability is anchored at the fleet coverage floor of 0.367, rounded to 0.37, with no upward adjustment due to lack of route-specific observations.
