Construction is moving faster than expected on the major expansion of the Des Moines International Airport, positioning the city for future growth in both tourism and business travel. The long-planned terminal project is now running ahead of schedule thanks to a boost in grant funding and accelerated planning efforts.
“We are projecting January 2027 to open the new terminal, and that will be initially with six gates. Then we will incrementally add gates as we complete construction. Originally, the last couple of gates toward Fleur Drive weren’t projected to be completed until after 2040,” said Brian Mulcahy, CEO of the Des Moines Airport Authority.
The airport is undergoing one of the largest infrastructure investments in its history, with the new terminal designed to replace aging facilities that currently struggle to keep pace with passenger traffic. Airport leaders say capacity challenges have been especially apparent during peak travel seasons, and delays in boarding and deplaning have become more frequent.
Once completed, the expanded terminal will feature 22 new gates, boosting aircraft capacity by nearly 50% and improving operational efficiency for airlines. The new design will also allow for more direct routes and future additions of international travel services — a significant economic advantage for Central Iowa.
Mulcahy emphasized that access to additional federal and state funding has been a game-changer in pushing the schedule forward. He said the airport was able to tap into multiple aviation grants and secure stronger financial partnerships, reducing the long-term wait for critical portions of the project.
Beyond gate expansion, travelers can expect improved circulation, modern amenities, and enhanced security screening technology designed to speed up the passenger experience. Accessibility upgrades, expanded concession spaces, and a more welcoming arrivals zone are also included in the plan.
Local tourism experts say the terminal will support Des Moines’ growing reputation as a host city for national conferences and major sports tournaments. Business leaders also point to increased air service as a key incentive for corporate investment and workforce relocation in the metro area.
Airport officials will continue adding gates through a phased construction schedule, with final completion targeted for late 2029. The project is part of a broader aviation infrastructure strategy expected to serve the region’s travel needs for decades.
