United Airlines is actively rolling out Starlink with about 52.2% fleet coverage, supported by multiple high-confidence news reports confirming initial Starlink-equipped flights on specific routes such as EWR-LAS and Boeing 737-800 aircraft. However, there are no direct observations or confirmed Starlink flights on the SEA-IAH route, and community sightings focus on regional routes rather than mainline transcontinental flights. Given the lack of route-specific observations and the fleet coverage ratio, the probability is anchored at the fleet coverage level (0.522) without exceeding it, reflecting moderate likelihood but no direct confirmation for this route.
