Des Moines International Airport (DSM)

Des Moines International Airport (DSM) is the premier aviation gateway to Iowa, serving as the primary commercial link for the state's capital and its largest metropolitan area. Managed by the Des Moines Airport Authority, the facility spans over 2,600 acres and plays a critical role in the regional economy, handling a record volume of nearly three million passengers annually. Its central location makes it an essential hub for business travelers and tourists alike, offering extensive domestic coverage through major carriers including American, Delta, and Southwest Airlines.

The current terminal infrastructure is organized into three distinct areas: the Main Terminal, Concourse A, and Concourse C. Concourse A features nine gates primarily serving Delta and United, while Concourse C houses four gates used by Allegiant Air and Frontier. The Main Terminal manages an additional 14 gates for American and Southwest, with all facilities interconnected by covered walkways and a complimentary shuttle service to ensure efficient passenger flow. Inside, travelers have access to a variety of modern amenities, including free high-speed Wi-Fi, Mamava nursing pods for families, and a diverse range of dining options from full-service restaurants to local Iowa-themed cafes.

To support the region's rapid growth, the airport has embarked on an ambitious multi-phase modernization project known as "Lift DSM." This $550 million initiative, which broke ground in 2023, aims to replace the legacy facilities with a state-of-the-art terminal complex designed by HNTB and BNIM. The new terminal, featuring a signature transparent glass facade and a distinctive wave-inspired roofline, is expected to open its first phase in January 2027. This expansion will nearly double the airport's capacity, introducing eight new security lanes, expanded baggage handling systems, and modernized gatehouses, ensuring that DSM remains a world-class regional facility for decades to come.
