United Airlines has an installed rollout status with a fleet coverage ratio of 51.9%, which mandates a minimum probability floor of 0.519 regardless of zero direct observations on the LGA->STL route. The zero observed Starlink flights on this route likely reflect 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 confirm completion of regional fleet rollout with 300+ aircraft equipped. Given the medium confidence in perplexity data and strong fleet coverage, the probability is anchored at fleet coverage with no upward adjustment due to lack of route-specific observations.
