Hi there! If you're wondering what terminal Southwest is at DCA, it's Southwest Airlines DCA Terminal, and I had a really smooth experience there. I flew to Atlanta last month and was relieved at how easy it was to find the Southwest check-in area right near the entrance. Security was fast, and even though the terminal is smaller than others, it felt cozy and well-organized. I grabbed a coffee at a nearby café before boarding. The Southwest staff were friendly, and everything ran on time. It’s not the fanciest terminal, but it definitely gets the job done efficiently and pleasantly!
