What Terminal is Southwest at FLL? The Southwest Airlines FLL Terminal is quite impressive! Everything went according to plan. Even during busy hours, TSA lines were low and baggage dropped quickly. Before my trip, I had time to unwind and get a bite to eat. For a large airport terminal, the ambiance seemed surprisingly relaxed. It's obvious that Southwest has a fantastic Fort Lauderdale setup. If you intend to take a flight with them out of FLL, this terminal will not let you down. It was undoubtedly a seamless experience.
