WestJet has a moderate fleet coverage of 55.5% for Starlink, indicating a potential for Starlink-equipped aircraft on this route. However, there are no direct observations or confirmed sightings on the YHM->CUN route, and no recent airline-specific news. The only relevant evidence is a community sighting of WestJet rolling out Starlink on a different route (YYC-YYZ). Given the absence of direct route data and the fleet coverage, the probability is anchored conservatively near zero but slightly elevated to 0.10 to reflect the ongoing rollout and fleet coverage.
