MAJOR PROJECTS AND INFRASTRUCTURE

Gate Expansion Program

Over the last 28 years, DEN has grown from 33.1 million annual passengers to 77.8 million passengers in 2023.

While passenger traffic slowed in 2020 and 2021 due to COVID-19, DEN was one of the fastest-recovering airports. DEN has outgrown its facilities which were built for 50 million passengers. In response, DEN is making many improvements to accommodate the continued growth, including expanding and enhancing Concourse A-West, Concourse B-West and B-East, and Concourse C-East.

DEN built 39 new concourse gates, increasing overall capacity at the airport by 30%. The new gates, on all three concourses, allow DEN’s airlines the opportunity to grow and for DEN to accommodate new airlines, including international carriers.

Gate Expansion Program Costs

Gate Expansion: Budgeted $2.5 billion

The original budget was $1.5 billion to construct 39 new gates. Once the gates were officially leased to United and Southwest, DEN added work to the program to accommodate the relocation of various airlines to other gates. This work includes the buildout of a new commuter facility, new airline support spaces, a new club for American Airlines on Concourse C and gate modifications and technology upgrades. The additional budget also allows for the construction of the ground load facility, including five new gates for Frontier Airlines. DEN is an enterprise of the City and County of Denver and does not operate using General Fund tax dollars.

In May 2018, DEN broke ground on the Gate Expansion Program. DEN opened the first completed area, B-West, in November 2020, C-East in May 2022, B-East in October 2022 and A-West in November 2022.

The commuter facility is located on the ramp level below gates C66 and C67 and is home to Boutique Air, and Denver Air Connection. The commuter airlines provide service to small communities across the Great Plains and Rocky Mountain regions, giving passengers in these areas access to larger air service networks at airports such as DEN.

The commuter facility consists of four gates for the three airlines, as well as comfortable seating with charging stations. In the future, passengers will also have access to eight new shopping and dining options that have opened in 2023, will continue to open on the concourse level in 2024.
