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 direct observations on the SDF->SLN 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 active Starlink use on United mainline flights, including inaugural flights and media tests, supporting the assumption that Starlink is widely available across their network. Community sightings confirm completion of rollout on regional fleets as well. Given the lack of route-specific observations but strong fleet-wide evidence, the probability is anchored at the fleet coverage level with high confidence.
