Southwest Airlines currently has a fleet coverage of 86.2% but the rollout status is 'rolling_out' with no aircraft equipped yet as of the latest verified context. There are zero observed flights with Starlink on the HOU->TUL route and no recent news or community sightings to suggest active deployment. Given the announced rollout starting summer 2026 and no confirmed equipped aircraft, the probability remains at zero despite the high fleet coverage potential. The fleet ratio is not treated as a floor here because the airline has not yet installed any Starlink units.
