United Airlines has a fleet coverage of 52.2% with Starlink equipped aircraft, indicating moderate availability. However, there are no direct observations of Starlink on the RDU->SFO route, so empirical observation is zero. Recent high-confidence news confirms Starlink rollout on United's mainline fleet, including inaugural flights from Newark and media tests on Boeing 737-800s, but no specific mention of RDU->SFO. Regional fleet rollout is complete but less relevant for this mainline route. Given the lack of direct route observations and moderate fleet coverage, the probability is anchored near the fleet coverage but adjusted downward to respect the zero observation rate, resulting in a conservative estimate of 0.42. Confidence is medium due to indirect evidence and absence of route-specific sightings.
