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 IAD->PWM route, the critical scoring rule for fully deployed airlines with fleet coverage above 50% mandates a minimum probability equal to the fleet ratio. Recent news confirms active Starlink installation on mainline aircraft and regional fleets, and community sightings verify completion of rollout on 300+ regional aircraft. Given the high fleet coverage and strong rollout status, the probability is anchored at 0.956 despite no direct route observations.
