United Airlines has a very high fleet coverage ratio of 95.6% with Starlink fully deployed across its fleet. Despite zero direct observations on the IAD->SAT route, the critical scoring rule mandates a minimum probability equal to the fleet coverage for fully deployed airlines with coverage above 50%. Recent news confirms active Starlink deployment on mainline aircraft including Boeing 737-800s, and community sightings verify completion of regional fleet rollout. Given the high fleet coverage and strong rollout status, the probability is anchored at 0.956 with high confidence.
