United Airlines has a fleet coverage of 51.9% with Starlink installed and rollout status marked as 'installed', which mandates a minimum probability floor of 0.519 for all routes regardless of zero direct observations on GUM->NGO. Although no flights on this route have confirmed Starlink tails, multiple high-confidence news reports and community sightings confirm widespread installation on United's regional and mainline fleets, including recent inaugural mainline flights with Starlink. Given the lack of direct route observations but strong fleet-wide evidence and rollout status, the probability is anchored slightly above the fleet ratio at 0.52 to reflect the likelihood of Starlink presence on this route.
