What does Denver International Airport do?

Denver International Airport (DEN) is a major international hub and one of the busiest airports globally, generating over $33.5 billion annually for Colorado's economy. Opened on February 28, 1995, it covers 53 square miles, making it the largest airport in the U.S. by land area. DEN serves over 82.4 million passengers and offers nonstop service to 230 destinations across the Americas, Europe, and Asia through 27 airlines. The airport features three key concourses: Concourse A, which serves multiple airlines including Alaska and Delta; Concourse B, exclusively for United Airlines; and Concourse C, primarily for Southwest and American Airlines. DEN is committed to sustainability, being the only U.S. airport with a fully ISO 14001-certified environmental management system. Ongoing infrastructure projects, such as the Great Hall Project, aim to enhance passenger experience and expand capacity, with completion projected for 2027. Through initiatives like the Center of Equity and Excellence in Aviation, DEN supports workforce development and economic growth in the region.
