United Airlines has a fleet coverage of approximately 52.2% with Starlink equipped aircraft, and recent news confirms active rollout and testing on mainline flights, including inaugural flights with Starlink WiFi. However, there are no direct observations of Starlink-equipped flights on the JAC->SFO route, and community sightings focus on regional routes rather than this specific mainline route. Given the lack of route-specific observations, the probability is anchored to the fleet coverage ratio, reflecting the rolling out status and recent news but no direct route evidence.
