United Airlines is actively rolling out Starlink with about 52.2% fleet coverage, supported by recent high-confidence news of initial Starlink flights on Boeing 737-800s and inaugural flights from Newark. However, there are no direct observations of Starlink on the IAD->MIA route, and community sightings focus on regional routes rather than mainline routes like IAD->MIA. Given the lack of route-specific observations and the fleet coverage slightly above 50%, the probability is anchored conservatively below the fleet coverage ratio, adjusted downward due to zero observed flights on this route but uplifted slightly due to recent news and rollout status.
