Changes

Denver was at a disadvantage in the 19th century because the transcontinental routes ran 200 miles north of the city, through Cheyenne, Wyoming, which became  the primary way station for wagon trains, stage lines, and rail lines passing through the northern Rockies. Pilots at first preferred Cheyenne, and it won the first round of competition when the US Post Office decided to fly mail through Wyoming in 1920. Denver business leaders never stopped competing, however, and struggled to get a share of the traffic. By the mid-1930s they convinced some passenger airlines to move their operations to Colorado. After World War II, Denver wrested full control of Rocky Mountain air traffic from Cheyenne, making the city's Stapleton airport the major regional hub.<ref>Roger D. Launius, and Jessie L.

Denver International Airport (DIA) is one of the world's ten busiest facilities and is the hub for United and Frontier airlines.  DIA has four north-south runways and two east-west runways. The concourses and Jeppesen Terminal (with its Teflon-coated fiberglass roof) are in the center of the airfield. 95 airlines operated 1175 passenger flights daily in 2006, with 130,000 passengers a day.  The airport is operating close to capacity and plans to spend $1 billion through 2013 on its concourses, concession areas, security checkpoints, parking lots and baggage system.<ref>See Chris Walsh, "DIA bursting at the seams," ''Rocky Mountain News'' September 29, 2007 at [http://www.rockymountainnews.com/drmn/airlines/article/0,2777,DRMN_23912_5710157,00.html]</ref> There are numerous flights to Mexico and Canada, and three to Europe. 44% of the passengers are making connections in Denver; Los Angeles is the chief point of origin.  DIA replaced inner-city Stapleton International Airport (1929-1995). Once open range country, the area near DIA is undergoing rapid construction of homes, hotels and warehouses.
