Alaska Airlines has a rollout status of 'installed' with a high fleet coverage ratio of 72.2%. Despite zero observed flights with confirmed Starlink on the SEA->BFI route, the critical scoring rule mandates that the probability cannot be below the fleet coverage ratio for installed airlines with fleet coverage above 50%. No recent news or community sightings affect this route specifically, so the probability is anchored at the fleet coverage ratio of 0.722. The confidence is medium due to the discrepancy between the high fleet coverage and zero observations, likely reflecting incomplete flight tracking data rather than absence of Starlink.
