United Airlines has a fleet coverage of approximately 52.2% for Starlink-equipped aircraft, indicating a moderate rollout stage. However, there are no direct observations of Starlink on the JAX to IAD route, resulting in a 0% empirical observation rate. Recent high-confidence news confirms Starlink installations on United's mainline fleet and inaugural flights from Newark, but no specific mentions of JAX to IAD. Regional fleet rollout is complete but less relevant for this mainline route. Given the lack of route-specific observations, the probability is anchored to the fleet coverage ratio, with no upward adjustment beyond 0.10 due to absence of direct route evidence, resulting in a conservative estimate of 0.52.
