United Airlines has a fleet coverage of approximately 52.2% for Starlink-equipped aircraft, indicating that about half of their fleet is outfitted. However, there are no direct observations of Starlink on the IAH->SYD route, and no route-specific sightings or news mention this long-haul international route. Recent news confirms rollout and initial flights with Starlink on domestic and regional routes, but no evidence specifically supports Starlink availability on this transpacific route yet. Given the lack of direct observations and route-specific evidence, the probability is anchored at the fleet coverage ratio of 0.52, reflecting the chance that a Starlink-equipped aircraft might be assigned to this route. The confidence is medium due to solid fleet data but no direct route observations.
