United Airlines has a fleet coverage of 52.2% for Starlink-equipped aircraft, indicating a moderate rollout stage. However, there are no direct observations of Starlink on the IAH->SNA route, so empirical observation ratio is 0%. Recent high-confidence news confirms Starlink is operational on United's mainline fleet, but specific route evidence for IAH->SNA is lacking. Regional fleet rollout is complete but less relevant for this mainline route. Given the absence of route-specific sightings and zero observed flights with Starlink, the probability is anchored at the fleet coverage ratio (0.522) without exceeding it, reflecting moderate likelihood but no direct confirmation.
