Southwest Airlines is currently in the announced rollout phase for Starlink with zero aircraft equipped as of the latest data. Although the fleet coverage is high at 86.2%, this reflects planned future installations rather than current status. There are no confirmed Starlink observations or community sightings on the TPA->MSY route, and no recent news indicating active deployment. Given the rollout status 'rolling_out' but with zero equipped aircraft, the probability must be anchored at the empirical observation rate of 0.0, reflecting no current Starlink availability on this route.
