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 PHX->ANC route, the critical scoring rule mandates using the fleet coverage ratio as the minimum probability for routes of airlines with installed status and 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 with medium confidence due to some uncertainty in rollout completeness and observation data.
