United Airlines has a fleet coverage of 51.9% with Starlink installed and rollout status 'installed', which mandates a minimum probability floor of 0.519 for all routes regardless of zero direct observations on PIT->CLT. Recent high-confidence news confirms active Starlink deployment on United's mainline and regional fleets, including over 300 regional aircraft fully equipped by early 2026. Although no direct observations exist on this route, the fleet coverage and rollout status strongly support a probability anchored at fleet coverage. The zero observation count is likely due to incomplete flight tracking data rather than absence of Starlink. Therefore, the probability is set at the fleet coverage floor with medium-high confidence.
