WestJet has a moderate fleet coverage of 55.5% for Starlink-equipped aircraft, indicating potential availability on some routes. However, there are no confirmed Starlink observations on the YLW->SEA route, and no recent airline-specific news or community sightings directly referencing this route. Given the zero observed rate on this route, the probability is anchored conservatively near zero but slightly elevated to 0.10 to reflect the rolling out status and moderate fleet coverage, without exceeding the empirical observation rate by more than 0.10 as per guidelines.
