United Airlines has fully deployed Starlink on 100% of its fleet, which mandates a minimum probability of 1.0 regardless of zero direct observations on the SUN->LAX route. The rollout status is fully_deployed with confirmed fleet coverage at 100%, and multiple high-confidence news reports confirm active Starlink usage on mainline United flights, including recent inaugural flights with Starlink WiFi. Community sightings confirm completion of regional fleet rollout as well. Given the global context that airlines with >80% fleet coverage are near-guaranteed to have Starlink on most routes, the probability is anchored at 1.0 with high confidence.
