United Airlines has a fleet coverage of approximately 52.2% with Starlink equipped aircraft, indicating a moderate likelihood of Starlink availability on any given flight. However, there are zero direct observations of Starlink on the ONT->DEN route, so empirical data does not support a high probability. Recent high-confidence news confirms rollout and initial flights with Starlink on United, but these are focused on other routes (EWR->LAS and Boeing 737-800 aircraft). Community sightings confirm regional fleet rollout but do not specifically mention this route. Given the lack of direct route observations and moderate fleet coverage, the probability is anchored at the fleet coverage ratio (0.522) without exceeding it, reflecting a cautious but optimistic estimate.
