United Airlines has an installed rollout status with a fleet coverage of 36.7%, which sets a floor for the probability score. Although there are zero confirmed Starlink observations on the IAH-LHR route, this is likely due to incomplete flight tracking data rather than absence of Starlink. Recent high-confidence news confirms that United is actively equipping mainline aircraft with Starlink, including inaugural flights on mainline routes. Community sightings confirm rollout completion on regional US routes, supporting ongoing expansion. Given the fleet coverage below 50% and zero observations, the probability is anchored at the fleet coverage floor (0.367) and rounded to 0.37, reflecting a likely but not confirmed presence of Starlink on this route.
