United Airlines has a moderate fleet-wide Starlink coverage of approximately 50.5%, indicating a substantial rollout. However, there are no direct observations of Starlink-equipped flights on the IAH->MZT route, and no specific news or sightings mention this route. Recent news confirms Starlink installations on mainline United aircraft and inaugural flights on other routes, but not this one specifically. Given the lack of route-specific observations and the fleet coverage ratio, the probability is anchored conservatively near the fleet coverage but slightly reduced due to zero direct observations and low confidence in some data points.
