United Airlines has a moderate fleet coverage of 50.5% Starlink-equipped aircraft, indicating a significant but not majority rollout. However, there are zero observed flights with confirmed Starlink on the ZLO->IAH route, so empirical observation is 0%. Recent news confirms Starlink installations primarily on mainline and regional aircraft, with inaugural flights on other routes but no specific mention of ZLO->IAH. Community sightings confirm regional fleet rollout completion but do not specify this route. Given the lack of direct route observations and moderate fleet coverage, the probability is anchored conservatively near the fleet coverage but adjusted downward due to zero observations and no route-specific news, resulting in a 0.40 estimate with possible confidence.
