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. Federal Aviation Administration records say the airport had 919,990 passenger boardings (enplanements) in calendar year 2008, 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 has been going on at the airport involving the complete reconstruction of runway 05/23 and ongoing (as of 9/14/2023) construction that has led 31/13 to be closed as well.

Terminal replacement

In April 2022, the Des Moines International Airport released their terminal study, calling for a new terminal building to be built, replacing the current one. Older plans capped the airport capacity to 17 gates, 5 more than their current terminal design. The new plan allows for a minimum of 18 gates with a further expansion option of up to 22 gates and 5 additional commercial aircraft parking spaces with the project being built in phases to mitigate costs. The plan also includes US Customs and Border Protection for the airport to allow processing of international passengers.

In May, the airport asked the surrounding towns and counties to contribute more than $2 million to the airport expansion plans. Work on the new terminal project isn't set to begin until 2024 with an estimated price tag of $769 million.

Facilities

The airport covers 2,625 acres (1,062 ha) at an elevation of 958 feet (292 m). It has two runways: 5/23 is 6,601 by 150 feet (2,012 x 46 m); 13/31 is 9,001 by 150 feet (2,744 x 46 m).
