The United Airlines DEN Terminal (DEN) is a clean, well-maintained facility. The security and check-in lines moved swiftly, and my gate was easy to locate because of the many signs. During my layover, I was fascinated by the terminal's numerous dining and retail options. Despite being quite packed during peak hours, the seating spaces were comfortable. I was pleased by the staff's friendliness and the cleanliness of the restrooms. All in all, it was a good experience, and I would take another flight through the United terminal in Denver.
