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 of Starlink on the GSP->IAH route, the rollout status is fully deployed and multiple recent high-confidence news reports confirm Starlink installation on mainline and regional fleets, including inaugural flights and media tests. Community sightings also confirm completion of regional fleet rollout. Given the critical scoring rule for fully deployed airlines with fleet coverage above 50%, the probability cannot be scored below the fleet ratio despite zero observations. The lack of direct route observations likely reflects incomplete flight tracking data rather than absence of Starlink. Therefore, the probability is anchored at the fleet coverage ratio of 0.956 with high confidence.
