Hello there! I flew out of the Southwest Airlines DCA Terminal without any problems. Even though it was six in the morning, the personnel was quite polite and the check-in desks were well-organized! I was surprised by how quickly security responded and how clearly the gates were marked. The terminal itself is contemporary and immaculate, featuring spotless facilities and comfortable seating sections. I found my gate without any problems and had a brief coffee before my departure. The simplicity of everything struck me, especially for a big airport like. Easily one of the best terminals I've ever experienced!
