United Airlines has a very high fleet coverage ratio of 95.6% with Starlink fully deployed, which sets a strong baseline probability. Although there are zero direct observations on the SAT->EWR route, the critical scoring rule mandates that the probability cannot be below the fleet ratio for fully deployed airlines with coverage above 50%. Recent high-confidence news confirms Starlink is operational on United's mainline fleet, including inaugural flights from Newark (EWR), supporting the likelihood of Starlink availability on this route. Community sightings confirm full regional fleet rollout but do not contradict mainline deployment. Given the lack of direct route observations but strong fleet and news evidence, the probability is anchored at fleet coverage level with high confidence.
