United Airlines has installed Starlink on 53.4% of its fleet, with strong rollout progress especially on regional aircraft (300+ equipped) and plans to reach over 800 planes soon. However, there are zero direct observations of Starlink on the HSV->IAH route, and no specific sightings or news confirming Starlink service on this route. Recent news confirms mainline Starlink flights started only recently and on different routes (EWR->LAS, Boeing 737-800). Given the fleet coverage and rollout status, the probability is anchored near the fleet coverage but slightly discounted due to lack of route-specific observations, resulting in a conservative estimate of 0.40.
