United Airlines has installed Starlink on 36.7% of its fleet, with rollout status 'installed' and medium confidence from Perplexity. Although there are zero direct observations on the IAD->SLC route, the critical scoring rule for 'installed' status with fleet ratio below 0.50 sets the floor at the fleet coverage ratio (0.367). Recent news confirms Starlink deployment on mainline United aircraft, but no specific sightings or observations exist for this route. Community sightings confirm regional fleet rollout completion but do not directly impact this mainline route. Therefore, the probability is anchored at the fleet coverage ratio, rounded to 0.37, reflecting a likely but not confirmed presence of Starlink on this route.
