United Airlines has a very high fleet coverage of 95.6% with Starlink fully deployed, which sets a strong baseline probability. Although there are zero observed flights with confirmed Starlink on the SCE-ORD 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 installation on mainline United aircraft, including inaugural flights and media tests, supporting the high probability. Community sightings confirm completion of regional fleet rollout but do not contradict mainline deployment. The lack of direct observations on this route likely reflects incomplete flight tracking data rather than absence of Starlink.
