It was a great trip from the United Airlines DCA Terminal. I was happy with the layout of the terminal and arrived two hours early. I followed signs that led me directly to the United check-in desks. Even in the morning rush, the queue for security went swiftly. There were some of the finest restrooms I've seen in an airport, and the waiting area was immaculate. The Wi-Fi was quick and simple to use, so I was able to finish some work. The United gate staff was well-organized and amiable, and the boarding announcements were prompt and apparent. My connecting flight was a question, and I had no issue getting help. United at DCA has excellent terminal standards and timely service; therefore, I will most certainly use them again.
