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 of Starlink on the TUS->SFO route, the rollout status is fully deployed and recent news confirms active Starlink usage on mainline United flights, including inaugural flights on Boeing 737-800s and other mainline routes. Community sightings confirm completion of Starlink installation on over 300 regional aircraft and ongoing expansion to more than 800 planes. Given the high fleet coverage and rollout status, the probability must be anchored at the fleet coverage ratio despite zero observations, as per critical scoring rules.
