Denver International Airport DENKDEN

Denver International Airport is one of the key connecting airports in the U.S. Mountain West. United has a very large hub here, giving DEN strong Star Alliance connectivity; Southwest and Frontier also treat Denver as a major operating base, while many other U.S. and international carriers round out the network. It is both a domestic megahub and a real international gateway, with service across North America plus selected long-haul links to Europe and Asia. The airport is simple in concept but large in scale: one Jeppesen Terminal for check-in, security, baggage claim and ground transport, then three airside concourses reached mainly by the underground train.
