Alaska Airlines has a high fleet coverage of 72.2% with Starlink installed, and rollout status is 'installed'. Despite zero observed flights with confirmed Starlink on the BZN->BOI route, the critical scoring rule mandates the probability not fall 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.
