United Airlines uses Washington Dulles International Airport (IAD) as a major hub. With an additional set of gates in Terminal B, United Airlines mostly operates out of Terminals C and D. In order to give its customers a smooth and pleasurable flying experience, the United Airlines IAD Terminal provides a wide range of amenities and services. International publications are part of this to serve the wide range of passengers. Some lounges offer showers so that travelers can freshen up before their trip. This is particularly convenient for individuals who are traveling long distances.
