United Airlines has a fleet coverage of 52.2% for Starlink-equipped aircraft, indicating a moderate rollout. However, there are no direct observations of Starlink on the ONT -> IAH route, and no route-specific sightings or news mention this route. Recent news confirms Starlink is operational on some United flights, but only on specific routes like EWR->LAS and initial Boeing 737-800 aircraft. Given the lack of direct route observations and the fleet coverage ratio, the probability is anchored at the fleet coverage level of 0.52, reflecting the chance that a flight on this route could be operated by a Starlink-equipped aircraft. Confidence is medium due to solid fleet data but absence of route-specific evidence.
