Route-specific score for SEA–SJC
Alaska Airlines is currently rolling out Starlink with a fleet coverage of 29.2%, slightly below the 30% threshold where fleet ratio acts as a floor. There are zero confirmed Starlink observations on the SEA->SJC route, and no recent news or community sightings to suggest higher coverage. Given the rollout status and medium confidence in the perplexity data indicating 66 equipped aircraft, the probability is anchored to the fleet coverage ratio of 29.2%. The lack of observations and news keeps the confidence moderate and the probability conservative.
