United Airlines has a very high fleet coverage of 95.6% with Starlink fully deployed, indicating near-guaranteed availability on most routes including TUS->IAH. Although there are zero direct observations on this route, the critical scoring rule mandates the probability floor to be the fleet coverage ratio for fully deployed airlines with coverage above 50%. Recent high-confidence news confirms active mainline Starlink installations and operational flights, and community sightings verify completion of regional fleet rollout. The zero observations likely reflect incomplete flight tracking data rather than absence of Starlink.
