Southwest Airlines has zero Starlink-equipped aircraft in its operational fleet (0 of 850 aircraft, 0% coverage). No observations on this route exist, no recent news confirms any rollout progress, and no community sightings have been reported. While Southwest is listed as 'rolling_out' status, the complete absence of equipped aircraft means Starlink WiFi is not yet available on any Southwest flights, including the BWI-DTW route. This represents a hard constraint - the airline cannot offer Starlink connectivity without equipped aircraft.
