Alaska Airlines has a high fleet coverage ratio of 72.2% with Starlink installed, and rollout status is 'installed'. Despite zero observed flights with confirmed Starlink on the SEA->BOS route, the critical scoring rule mandates using the fleet coverage ratio as a minimum probability floor. No recent news or community sightings affect this route specifically, so the probability is anchored at the fleet ratio of 0.722. The confidence is medium due to lack of direct route observations but high confidence in fleet data.
