Des Moines International Airport

Des Moines International Airport is a joint civilian-military commercial service airport 5 miles (8 km) southwest of Des Moines, the capital of Iowa.

The airport's campus includes two runways, 46 buildings, seven parking facilities, and the terminal. Six commercial airlines offer service from DSM (American, Allegiant, Delta, Frontier, Southwest, and United). The airport is managed by the Des Moines Airport Authority.

The National Plan of Integrated Airport Systems for 2017–2021 called it a primary commercial service airport. In 2016 a record 2.48 million passengers used the airport, up 5 percent from 2015. In 2019, DSM served 2.92 million passengers, a record for the airport.

The airport hosts the 132nd Wing of the Iowa Air National Guard.

History

In the 1920s the Des Moines area had several small airports for general aviation and airmail. In 1929, the Iowa General Assembly passed a law allowing cities to sell bonds and levy assessments to build municipal airports. Over 80 sites were considered for the Des Moines Airport until a decision was made to build on 160 acres (0.65 km²) of farmland south of the city. Construction of the airport began in 1932 and was completed in 1933. The airport's first passenger terminal was built shortly after the airport was completed. It was replaced by a new terminal in 1950 that has been expanded and renovated several times. The present concourses were built in 1970, along with the remodeling of the terminal. The airport itself has expanded several times from its original site and now covers 2,625 acres (10.6 km²).

The airport was originally governed by the City of Des Moines' Parks Department. A separate Aviation Department was established by the city during the 1960s, and in 1982, a separate Aviation Policy Advisory Board was established. The airport was renamed the Des Moines International Airport in 1986 to acknowledge the presence of a United States Customs Service office at the airport.

In 2011, the City of Des Moines transferred control from the city to the Des Moines Airport Authority. The city retains ownership of the land but transfers title to all property and equipment to the public authority. In turn, the authority agreed to a 99-year lease on the land.

In 2016, a record 2.48 million passengers used the airport, up 5 percent from 2015. 853,596 in 2009 and 932,828 in 2011.

In July 2021, the airport announced plans to become a base for Allegiant Air.

Expansion

Interior renovation work began in 2009 on the airport and concluded in 2010. The project, designed by Brooks Borg Skiles AE LLP, included new carpets, paint, gate counters, seating, a new ceiling, signage, and a fire sprinkler system. Also included in the upgrade was a common-use project allowing any airline to use any gate at the airport. A new restroom was also added to the C concourse to allow for future concourse expansion. The airport modernized baggage handling capabilities with expanded processing facilities as well.

In addition to work inside the passenger terminal, the airport was building a rental car facility and new parking facilities.

Throughout 2022 and 2023, major construction at the airport involved the complete reconstruction of runway 05/23, and ongoing (as of September 2023) construction that led 31/13 to be closed as well.

Airfield and Terminal Improvements

As part of a multi-year expansion project known as "LiftDSM," the airport is undergoing a major reconfiguration of its terminal and airfield to meet passenger growth.

New Terminal

The airport broke ground on a new, larger terminal in October 2023. The $445 million project is the centerpiece of the LiftDSM initiative and will replace the current 1948-era terminal. The new facility will initially feature 18 gates, increasing the airport's capacity by 50%, and is scheduled to open in 2026.

Centralized De-icing Pads

In June 2024, the Des Moines Airport Authority awarded a $12.28 million contract for the construction of four new centralized de-icing pads. The pads, which are scheduled for completion in October 2025, will allow aircraft to be de-iced at a dedicated location instead of at the passenger gates. This change is intended to improve operational efficiency and reduce taxiing delays during winter weather. The project also includes the purchase of a snowmelting unit, and the new facility will be operated by Integrated Deicing Systems (IDS).
