I am a traveler and recently visited the Southwest Airlines DCA Terminal and the check-in process was quick and simple. The terminal was well-kept and simple to navigate. While I waited for my trip, I appreciated the cozy seating sections and charging stations. From small snacks to larger meals, there were plenty of food options available. All in all, it's a convenient terminal that made my trip pleasurable. Without a doubt, I would pick Southwest Airlines once more.
