Des Moines International Airport at a Glance

• Two long runways to accommodate commercial and military flights

The Des Moines Airport Authority oversees the airport, providing effective management and planning for future growth. DSM is served by six major airlines: American Airlines, Delta Air Lines, United Airlines, Southwest Airlines, Frontier Airlines, and Allegiant Air, providing extensive domestic routes.

History of Des Moines International Airport

Des Moines International Airport has its origins in the early 20th century, with several small airports in operation. In 1929, the state legislature allowed the city to build a municipal airport.

• Construction began in 1932 and was completed in 1933

• The passenger terminal soon after

• It was replaced with a larger terminal in 1950 and has been upgraded several times

The airport has grown from its initial 160 acres to more than 2,600 acres today. It was renamed in 1986 to reflect its status as an international airport, as it had customs services.

In 2011, the airport was transferred to the Des Moines Airport Authority, paving the way for recent development.

Terminal and Facilities

DSM has a single terminal with two concourses for quick and convenient travel. Concourses A and C serve all airlines with flexible gate assignments.

• Concourse A : Southwest, United, Allegiant

The airport also includes:

The airport has undergone recent upgrades (2009-2010) to enhance passenger comfort with improved signage, interior design, and flexible gate allocation.

Airfield and Runways

The airport has two intersecting runways:
