The majority of Denver flights land at Denver Intl. Airport (DEN). This airport, commonly referred to as DIA, is the largest airport in the United States and the second largest in the world. In addition, DIA is home to the longest public use runway in the country, and it is the 11th busiest airport in the world when ranked by passenger traffic. Airlines that have a major presence at DIA include Frontier Airlines, Great Lakes Airlines, United Airlines and Southwest Airlines. DIA is a rather unique looking airport; it's covered by a white Teflon-coated fiberglass roof that resembles the Rocky Mountains in an abstract sort of way.
