Denver International (DEN)
Denver International (DEN) at a glance
Denver International Airport is the newest major airport in the United States, opened in 1995, and now one of the ten busiest in the world, handling 82.4 million passengers in 2024 and holding its global top-ten place again in 2025. Its 135 square kilometer footprint is the largest of any airport in the Americas, master-planned for up to 12 runways against today's six.
Denver thrives on a three-way contest: United's hub at Concourse B, Southwest's largest station at Concourse C and a big Frontier base keep fares low and traffic booming, growth that has outpaced almost every US rival since the pandemic. The Vision 100 programme is expanding all three concourses and the Great Hall to ready the airport for 100 million passengers.
