Route-specific score for STL–SMF
Southwest Airlines currently has a fleet coverage of 86.2% planned but has not yet equipped any aircraft with Starlink as of the latest data (May 2026). The rollout status is 'rolling_out' with an announced start in summer 2026, and no confirmed observations or sightings on the STL->SMF route exist. Given the absence of equipped aircraft and zero observations, the probability of Starlink availability on this route is effectively zero at this time.
