United Airlines has installed Starlink on 51.9% of its fleet, with rollout status 'installed', which mandates a minimum probability floor of 0.519 despite zero direct observations on the ORD->ONT route. Recent high-confidence news confirms Starlink deployment on mainline aircraft including Boeing 737-800s, and community sightings verify completion of regional fleet rollout. However, no direct route-specific observations exist, so the probability is anchored at fleet coverage without upward adjustment.
