Although Southwest Airlines has a high overall fleet coverage ratio of 86.2%, the rollout status is 'rolling_out' with no aircraft currently equipped as of the latest verified context. There are zero observed flights with confirmed Starlink on the PHX->MSY route, and no recent news or community sightings support higher probability. Given the announced rollout starting summer 2026 and current zero equipped aircraft, the probability remains anchored at 0.0 with low confidence in any higher estimate.
