Route-specific score for IAD–SAT
United Airlines has an installed rollout status with a fleet coverage of 36.7%, which sets a floor for the probability at 0.367. Although there are zero observed flights with confirmed Starlink on the IAD->SAT route, this is likely due to incomplete flight tracking data rather than absence of Starlink. Recent high-confidence news confirms Starlink installation on United's mainline and regional fleets, and community sightings indicate rollout completion on regional US routes. Given the fleet coverage below 50% and zero observations, the probability is anchored at the fleet ratio floor of 0.367, rounded to 0.37, with a 'likely' confidence tier reflecting moderate certainty.
