United Airlines has a moderate fleet coverage of 50.5% Starlink-equipped aircraft, indicating a significant portion of their fleet is outfitted. However, there are no direct observations of Starlink on the GVA->IAD route, and no specific sightings or news mention this route. Recent news confirms Starlink rollout on United's mainline fleet, but only on select routes such as EWR->LAS, not GVA->IAD. Given the lack of route-specific observations and the fleet coverage, the probability is anchored near the fleet coverage but adjusted downward to reflect zero observed flights on this route, resulting in a conservative estimate of 0.40. The confidence is medium due to moderate fleet data and indirect news evidence but no direct route observations.
