United Airlines has a moderate fleet coverage of 52.2% with 522 aircraft equipped, and recent news confirms active rollout and initial Starlink flights primarily on Boeing 737-800 and select routes like Newark to Las Vegas. However, there are zero direct observations of Starlink on the BOS->SFO route, and community sightings focus on regional routes rather than mainline transcontinental flights. Given the lack of route-specific observations and the fleet coverage slightly above 50%, the probability is anchored below fleet coverage but elevated by rollout news and fleet size, resulting in a conservative estimate of 0.35.
