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 observed flights with confirmed Starlink on the BDL->DEN 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 on mainline aircraft. Community sightings also confirm rollout completion on regional US routes. Given the fleet coverage and rollout status, the probability is anchored at the fleet ratio floor of 0.37 with medium confidence.
