United Airlines has a moderate fleet coverage of 50.5% for Starlink installations, but there are zero observed flights with confirmed Starlink on the IAD-ZRH route. Recent news confirms Starlink rollout on United's mainline fleet, but sightings and observations are primarily focused on US domestic and regional routes, with no specific evidence for this transatlantic route. Given the lack of direct observations and route-specific sightings, the probability is anchored conservatively near zero, but adjusted upward slightly due to fleet coverage and rollout news.
