Denver International Airport (DEN) will add 11 gates to Concourse C as air traffic grows in the city, according to an announcement.
The $700 million extension to the western end of C, known as “C-West,” will add 400,000 more square feet to the concourse for the 11 gates and new concessions, as well as a new outdoor patio with panoramic views of the Rocky Mountains. The expansion is expected to be completed by 2030 or 2031.
The project, said the announcement, is part of DEN’s “Vision 100” program to expand the airport’s facilities to accommodate a forecasted 100 million annual passengers within the next decade. DEN handled a record 82.4 million travelers in 2024.
The C-West extension comes three years after DEN completed a 39-gate expansion of its three concourses. Those gates were taken by Southwest Airlines and United Airlines to support their rapidly growing hubs at the airport.
Southwest and United, according to news reports, are the most likely beneficiaries of the expansion, as they are driving much of DEN’s traffic growth. Southwest, the main tenant in Concourse C, could expand into the new gates — or Delta Air Lines could move from Concourse A, allowing United to expand its presence in A.
United executives have said they want to grow the airline’s DEN hub to around 700 daily departures, up from the current 575.
