Southwest Airlines is currently in the announced rollout phase for Starlink with zero aircraft equipped as of the latest data. Although the fleet coverage for equipped aircraft is 86.2%, this figure is not yet realized since rollout has not started and no flights on the RDU->DAL route have confirmed Starlink presence. No recent news or community sightings support higher probability. Therefore, the probability is anchored at 0.0 reflecting current reality despite the high fleet coverage target.
