WestJet has equipped 95% of its fleet with Starlink and is in rolling_out status. Although there are zero direct observations on the CUN->YLW route, the very high fleet coverage and recent community sightings on a similar route (YYC-YYZ) strongly support near-guaranteed Starlink availability on this route. According to the critical scoring rule, for airlines with rolling_out status and fleet coverage above 0.30, the fleet ratio acts as a floor, so the probability is anchored at 0.95 despite zero observations.
