United Airlines has installed Starlink on over 300 regional aircraft and aims for more than 800 equipped planes by end of 2026, representing a fleet coverage of 53.4%. However, there are no direct observations of Starlink on the PHX->IAD route, and recent news highlights initial mainline deployments primarily on other routes such as EWR->LAS. Given the medium confidence in rollout status and absence of route-specific sightings, the probability is anchored slightly below fleet coverage at 0.40, reflecting likely but not confirmed presence on this route.
