United Airlines has installed Starlink on 53.4% of its fleet, with confirmed rollout on 300+ regional aircraft and plans to reach over 800 planes soon. However, there are zero direct observations of Starlink on the BZN->IAH route, which suggests limited or no current deployment on this specific route. Recent high-confidence news confirms Starlink on mainline United flights but only on select routes (e.g., EWR->LAS). Given the fleet coverage and rollout status, a probability anchored near the fleet ratio but slightly reduced due to zero observations is appropriate, resulting in a conservative estimate around 0.40.
