United Airlines is actively rolling out Starlink WiFi with approximately 52.2% fleet coverage, supported by multiple high-confidence news reports confirming initial Starlink flights on specific routes and completion of regional fleet installations. However, there are zero direct observations of Starlink-equipped flights on the IAH-PHL route, and no recent sightings specific to this route. Given the fleet coverage and rollout status, the probability is anchored to the fleet coverage ratio of 52.2%, with no observational data to suggest a lower or higher rate. Therefore, a conservative estimate aligns with the fleet coverage ratio, reflecting possible but unconfirmed presence of Starlink on this route.
