Iowa Airports: Complete Guide to Commercial & Regional Airports

Des Moines International Airport (DSM) is Iowa's largest airport, handling 3.18 million passengers in 2024. Located 5 miles southwest of downtown Des Moines at 5800 Fleur Drive, DSM accounts for approximately 66% of Iowa's air passenger traffic and offers the most destinations with 33 nonstop routes served by 6 airlines: American, Allegiant, Delta, Frontier, Southwest, and United.

The airport set a new record in 2024 with 2.6% passenger growth compared to 2023, marking the second consecutive year exceeding 3 million travelers. Major expansion projects are underway, including a new terminal scheduled for completion in 2027 that will add 18 new gates and modernize amenities.

Iowa has 104 public-owned airports as of 2025, divided into two main categories:

• 8 Commercial Service Airports: These provide scheduled passenger airline service, including Des Moines International (DSM), Eastern Iowa Airport (CID), Sioux Gateway (SUX), Waterloo Regional (ALO), Dubuque Regional (DBQ), Southeast Iowa Regional (BRL), Mason City Municipal (MCW), and Fort Dodge Regional (FOD).
• 96 General Aviation Airports: These primarily support private flying, business aviation, flight training, agricultural aviation, emergency medical services, and recreational flying across Iowa's rural and urban communities.

Additionally, Iowa residents also use Quad City International Airport (MLI) in Moline, Illinois, which serves the Iowa/Illinois border region including Davenport and Bettendorf.

Only two Iowa airports currently offer TSA PreCheck expedited security screening:

• Des Moines International Airport (DSM): PreCheck screening available at the main concourse security checkpoint
• Eastern Iowa Airport (CID): PreCheck screening available, plus an on-site enrollment center operated by Telos Corporation at 2121 Arthur Collins Parkway, Cedar Rapids. The enrollment center is open Tuesdays and Thursdays from 8:30am-12:00pm and 12:30pm-4:00pm (by appointment only).

Smaller regional airports like Sioux Gateway (SUX), Waterloo (ALO), Dubuque (DBQ), Burlington (BRL), Mason City (MCW), and Fort Dodge (FOD) do not currently offer TSA PreCheck screening.

For TSA PreCheck enrollment, the cost is $78 for a 5-year membership. Starting May 1, 2025, applicants must provide a REAL ID-compliant driver's license or passport. Off-site enrollment locations include a Goodwill location in Fort Dodge (2735 5th Ave S) and occasional AAA office events in Iowa City.

Eastern Iowa Airport (CID) in Cedar Rapids is served by 5 airlines offering nonstop service to 21 destinations:

Sioux Gateway Airport's code "SUX" has been a source of both controversy and eventual pride for Sioux City. The three-letter IATA airport code phonetically sounds like the slang word "sucks," which Sioux City Mayor Craig Berenstein described as an "embarrassment" to the city in 2002.

Attempts to Change: The airport petitioned the Federal Aviation Administration (FAA) for a new identifier in both 1998 and 2002. However, the FAA-offered alternatives - GWU, GYO, GYT, SGV, and GAY - were deemed unappealing by local authorities, who ultimately elected to keep SUX.

Embracing the Code: Rather than continue fighting the designation, Sioux Gateway Airport has since embraced its unique code with humor and clever marketing. The airport now sells merchandise featuring the slogan "Fly SUX," turning what was once seen as a negative into a memorable brand that helps the airport stand out.

Airport Today: Sioux Gateway (SUX) completed a $6.2 million terminal renovation in 2011 (78% funded by federal and state grants) and continues to serve northwest Iowa with daily United Express flights to Chicago and Denver.

Eastern Iowa Airport (CID) in Cedar Rapids is Iowa's leading cargo airport, handling approximately 50% of the state's total air cargo volume. The airport processes over 40,000 tons (33 million pounds) of air freight annually through three major carriers: UPS, FedEx, and DHL, plus United States Postal Service Express Mail.

UPS Gateway Status: Since 1987, UPS has operated an air cargo "gateway" at CID, designating Cedar Rapids as a "central input point" for the company's Next Day Letter and Pak overnight freight service throughout the continental United States. Interestingly, the Cedar Rapids area generates more next-day business for UPS than Des Moines.

Recent Investments: UPS opened a new $18 million, 53,800-square-foot cargo facility at CID, creating 100 jobs. The facility typically handles Airbus A300 widebody freighters with 120,000-pound payloads, though Boeing 757s are occasionally used depending on network needs. FedEx has also invested $108.6 million in a warehouse and distribution center at 1035 Commerce Park Drive SW.

Competition: While CID dominates Iowa cargo operations, Des Moines International (DSM) has shown competitive growth, with some months exceeding CID's cargo volume. Des Moines has FedEx operations at 6233 SW 28th St.

Future Plans: Eastern Iowa Airport aims to become "known as the cargo airport for the state," with ongoing facility expansions designed to accommodate e-commerce growth and expanded freight operations.

Iowa airports do not currently offer scheduled international flights to foreign countries. Des Moines International Airport (DSM) is Iowa's only designated international airport, but "international" refers to its customs and immigration facilities rather than regular international service.

International Connections: Iowa travelers can reach international destinations through one-stop connections at major hub airports served by Iowa airports:

• Chicago O'Hare (ORD): Heavily served from both DSM and CID with 50+ and 59 weekly flights respectively - offers extensive international connections
• Denver (DEN): United hub with international flights to Mexico, Canada, Europe, and Asia
• Dallas/Fort Worth (DFW): American Airlines hub with flights to Latin America, Europe, and Asia
• Atlanta (ATL): Delta's largest hub offering worldwide connections
• Minneapolis (MSP): Delta hub with Canadian and European routes

Customs Facilities: Des Moines International has U.S. Customs and Border Protection facilities to handle charter flights, private international arrivals, and emergency diversions requiring customs clearance.

Canadian Access: The closest international airports with direct scheduled service are in neighboring states: Minneapolis-St. Paul (MSP) 3.5 hours north offers extensive Canadian connections, while Chicago O'Hare (ORD) 4 hours east is one of America's premier international gateways.

Essential Air Service (EAS) is a federal government program that subsidizes commercial air service to small and rural communities that would otherwise lack airline service due to insufficient passenger demand. The program ensures these communities maintain vital connections to the national air transportation system.

Iowa Airports Receiving EAS:

• Fort Dodge Regional Airport (FOD): Receives EAS subsidies for United Express service (operated by SkyWest Airlines) with direct jet flights to Chicago O'Hare (ORD). The federal contract has been extended through March 31, 2027.
• Southeast Iowa Regional Airport (BRL) in Burlington: Airline service subsidized under EAS at a cost of $1,917,566 per year. The airport is categorized as a non-primary commercial service airport with between 2,500 and 10,000 annual enplanements.

Why EAS Matters: Without EAS subsidies, airlines would likely discontinue service to these smaller markets as the routes don't generate sufficient revenue to operate profitably. The program maintains critical connections for business travelers, emergency medical transport, and economic development in rural Iowa communities.

Recent Investments: Fort Dodge Regional Airport received $1.2 million in federal grants to replace outdated taxiway lighting and reconstruct two taxiways, plus an additional $375,000 from the Iowa Department of Transportation for rehabilitation projects, demonstrating ongoing commitment to maintaining rural air service infrastructure.

Program Context: EAS was created in 1978 with airline deregulation to ensure small communities wouldn't lose all air service. Iowa's EAS airports connect to major hubs where passengers can reach hundreds of domestic and international destinations.
