WestJet has a very high fleet coverage of 95% with 151 of 159 aircraft equipped and a rollout status of 'rolling_out'. Although there are zero direct observations on the YYZ->BON route, the critical scoring rule for airlines with rollout_status 'rolling_out' and fleet_ratio >= 0.30 treats the fleet ratio as a floor, not a ceiling. Given the near-guaranteed coverage for airlines above 80% fleet coverage and no contradictory news or sightings, the probability is anchored at the fleet coverage ratio of 0.95 with high confidence.
