United Airlines has installed Starlink on over 50% of its fleet (53.4%), with confirmed rollout on 300+ regional aircraft and plans to reach 800+ equipped planes soon. However, there are zero direct observations of Starlink on the ORD->SDF route, and recent news highlights initial mainline deployments primarily on other routes (EWR->LAS). Given the lack of route-specific sightings and zero observed flights with Starlink on ORD->SDF, the probability is anchored conservatively near the fleet coverage but slightly discounted to 0.40 to reflect route variability and absence of direct evidence.
