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 GNV->SLC route, the critical scoring rule mandates a minimum probability equal to the fleet coverage ratio for 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 ratio of 0.722 with medium confidence due to the medium confidence in perplexity data and lack of direct route observations.
