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 PHL->SEA route, the critical scoring rule mandates using the fleet ratio as a minimum probability for installed airlines with fleet coverage above 50%. No recent news or community sightings exist to adjust this estimate. The observation data is incomplete and does not contradict the fleet coverage, so the probability is anchored at 0.722.
