United Airlines has a fleet coverage of 52.2% for Starlink-equipped aircraft, indicating a moderate rollout stage. However, there are no direct observations of Starlink on the IAH->SMF route, so the empirical observation ratio is 0.0%. Recent high-confidence news confirms that United is actively rolling out Starlink installations, including inaugural flights on other routes, but no specific mention of IAH->SMF. Community sightings confirm regional fleet rollout completion but do not specify this route. Given the lack of direct route observations, the probability is anchored to the fleet coverage ratio of 52.2%, without exceeding it, reflecting a likely but not confirmed presence of Starlink on this route.
