United Airlines has a moderate fleet coverage of 53.4% Starlink-equipped aircraft, with confirmed installation on over 300 regional planes and plans to exceed 800 by year-end. However, there are zero direct observations of Starlink on the INT->IAH route, and recent news highlights Starlink primarily on regional and select mainline routes like EWR->LAS and the first 737-800 retrofit. Given the lack of route-specific sightings and the fleet coverage ratio, the probability is anchored conservatively near the fleet coverage but slightly reduced to reflect no direct observations and limited mainline rollout evidence on this route.
