United Airlines has installed Starlink on over 300 regional aircraft and aims for over 800 total by end of 2026, representing a 53.4% fleet coverage. However, there are no direct observations of Starlink on the ORD->GSP route, and this route is likely served by regional aircraft with partial Starlink rollout. Recent news confirms mainline Starlink flights started only recently and primarily on other routes. Given zero observed flights with Starlink on this route, the probability is anchored below fleet coverage, adjusted downward to 0.40 to reflect lack of direct observations but supported by rollout status and regional fleet coverage.
