Hey, I am Carry and I recently visited Southwest Airlines DCA Terminal offers a smooth and efficient travel experience. The check-in process is quick, with friendly staff and clear signage. Security lines tend to move swiftly, and the terminal features ample seating, clean restrooms, and a variety of dining options. While it can get crowded during peak times, the overall atmosphere is relaxed. It's a convenient, no-frills terminal for passengers flying with Southwest, making it a pleasant pre-flight experience.
