Route-specific score for ONT–SEA
Alaska Airlines currently has a low fleet coverage of 9.7% for Starlink-equipped aircraft, with no confirmed Starlink observations on the ONT->SEA route. The rollout is announced but only beginning, with no recent news or community sightings supporting higher probability. Given the zero observed rate and low fleet coverage, the probability is anchored near the observation rate (0.0) but allowed a slight increase (up to 0.10) due to the announced rollout status and medium confidence in the announcement.
