Route-specific score for SEA–IAD
Alaska Airlines has a fleet coverage of 72.2% with Starlink installed, and rollout status is 'installed'. Although there are zero observed flights with confirmed Starlink on the SEA->IAD route, the critical scoring rule mandates that the probability score must not be below the fleet coverage ratio for airlines with installed status and fleet ratio above 0.50. No recent news or community sightings affect this route specifically, so the probability is anchored at the fleet coverage ratio of 0.722 with medium confidence due to the lack of direct route observations.
