Alaska Airlines has a fleet coverage ratio of 72.2% with Starlink installed, and rollout status is 'installed'. Despite zero observed flights with confirmed Starlink on the SLC->SAN route, the critical scoring rule mandates the probability not fall below the fleet ratio for installed airlines with fleet coverage above 50%. No recent news or community sightings exist to adjust the probability upward or downward. Flight observation data is incomplete and thus not reliable to lower the score.
