Southwest Airlines is currently in the rollout phase with a high fleet coverage ratio of 86.2%, which typically suggests a high probability of Starlink availability on routes. However, there are zero observed flights with confirmed Starlink on the BWI->MYR route, and no recent news or community sightings to support a higher probability. The rollout is announced to begin in summer 2026 with no current equipped aircraft, so the probability is anchored conservatively below fleet coverage but above zero due to the announced rollout status and high fleet coverage. This results in a moderate probability estimate reflecting potential imminent deployment but no current confirmed usage on this route.
