Southwest Airlines is currently in a rolling_out status with a very high fleet coverage ratio of 86.2%, indicating near-guaranteed Starlink presence on most routes once rollout begins. Although there are zero observed flights with confirmed Starlink on the TPA->GRR route and no recent news or sightings, the fleet coverage ratio serves as a strong floor for probability. Per critical scoring rules, for rolling_out airlines with fleet coverage above 0.30, the fleet ratio is treated as the minimum probability. Given the announced rollout starting summer 2026 and no current equipped aircraft, the probability is anchored at fleet coverage, reflecting high likelihood but not confirmed presence yet.
