United Airlines has installed Starlink on 53.4% of its fleet, with over 300 regional aircraft equipped and plans to reach 800+ by end of 2026. However, there are zero direct observations of Starlink on the IAD->ATL route, and recent news highlights initial mainline deployments primarily on other routes such as EWR->LAS. Given the fleet coverage and rollout status, the probability is anchored near the fleet coverage ratio (0.534) despite no route-specific observations, with a slight upward adjustment due to confirmed mainline installations and media flights. This results in a conservative estimate of 0.53 probability with likely confidence.
