Hey, I am Carry and I recently visited the Southwest Airlines DCA Terminal which is efficient and well-organized. Check-in and security are streamlined, making the travel experience relatively stress-free. The terminal is clean and offers a decent selection of food and retail options, though not extensive. Gate areas are spacious, but seating can be limited during peak hours. Overall, it's a comfortable and convenient terminal for travelers, with helpful staff and quick access to the airport's amenities.
