United Airlines has fully deployed Starlink on 100% of its fleet, including 1000 aircraft, which sets a minimum probability floor of 1.0 regardless of zero direct observations on the LAX->SUN route. Recent high-confidence news confirms Starlink is operational on mainline United aircraft, including Boeing 737-800s, and community sightings verify completion of regional fleet rollout. Given the global context that airlines with >80% fleet coverage are near-guaranteed on most routes, and United's full fleet coverage, the probability is anchored at 1.0 with high confidence despite no direct route observations.
