United Airlines has a very high fleet coverage ratio of 95.6% with Starlink fully deployed across its fleet. Although there are zero direct observations on the ORD->SCE route, the critical scoring rule mandates using the fleet coverage ratio as a minimum probability for fully deployed airlines with coverage above 50%. Recent high-confidence news confirms Starlink installation on mainline United aircraft including Boeing 737-800s, and community sightings verify completion of regional fleet rollout. Given the lack of route-specific observations but strong fleet-wide evidence and rollout status, the probability is anchored at the fleet coverage ratio with high confidence.
