United Airlines has installed Starlink on 53.4% of its fleet, with strong rollout evidence especially on regional aircraft and recent news confirming mainline Starlink flights starting late 2025 and early 2026. However, there are zero direct observations on the MLB->ORD route, and fleet coverage is moderate, so the probability is anchored below the fleet coverage ratio. Given the lack of route-specific sightings but positive rollout news and medium perplexity confidence, a conservative estimate slightly below fleet coverage is appropriate.
