United Airlines has installed Starlink on over 50% of its fleet (53.4%), including most of its regional two-cabin aircraft, with rollout continuing toward 800+ planes. However, there are zero direct observations of Starlink on the TUS-ORD route, and no confirmed sightings specific to this route. Recent news confirms Starlink use on mainline United flights but on different routes (EWR-LAS, regional US routes). Given the fleet coverage and rollout status, the probability is anchored near the fleet ratio but adjusted downward due to lack of direct route observations, resulting in a conservative estimate of 0.40.
