United Airlines has installed Starlink on over 300 regional aircraft and is rolling out to reach over 800 planes soon, representing a fleet coverage of 53.4%. However, there are no direct observations of Starlink on the GUM->MAJ route, and this route is not specifically mentioned in recent news or community sightings. Given the medium confidence in rollout status and the lack of route-specific data, the probability is anchored below the fleet coverage ratio, adjusted downward to 0.40 to reflect uncertainty and no direct observations. Recent news confirms mainline Starlink flights but on different routes, and community sightings focus on regional US routes, not this Pacific route.
