WestJet has a moderate fleet coverage of 55.5% for Starlink, indicating potential for Starlink-equipped aircraft on routes. However, there are zero observed flights with confirmed Starlink on the YUL-SXM route, and no route-specific news or sightings in the last 30 days. The only relevant evidence is a general community sighting of WestJet rolling out Starlink across its fleet on a different route (YYC-YYZ). Given the lack of direct observations and news for this route, the probability is anchored conservatively near zero but slightly elevated to 0.10 to reflect the fleet rollout status and moderate fleet coverage.
