Denver International is the largest airport in North America by land area, and its white peaked fabric roof was designed to echo both the snowcapped Rockies on the horizon and the tents of Plains encampments. Sitting at 1,655 meters of elevation, the thinner air means aircraft need longer takeoff runs — which is why one of its runways is the longest public-use runway in North America. The current schedule feed lists 245 airports in 22 countries connected to Denver.
It is a hub for United and Frontier and one of Southwest's largest bases. Visitors are greeted outside by 'Blue Mustang', the 32-foot blue horse with glowing red eyes that locals call Blucifer.
