Southwest Airlines currently has a high fleet coverage ratio of 86.2%, which would normally suggest a high probability of Starlink availability on routes. However, the rollout status is 'rolling_out' with no aircraft currently equipped, zero observed flights with Starlink on this route, no recent news, and no community sightings. Given the announced rollout starting summer 2026 and no current equipped aircraft, the probability is anchored low but not zero to reflect imminent rollout plans. The probability is conservatively set at 0.10 to reflect the announced rollout without current operational evidence.
