Choosing the right airline for a trip out of Des Moines International Airport (DSM) can make or break your travel experience. Six carriers currently operate from the terminal, offering a blend of nonstop routes, reliable connections, and fare structures that cater to everyone from business road warriors to vacationing families. This guide goes beyond the basics, examining each airline's network strengths, hidden fees, loyalty perks, and on-time track records so you can book with clarity and confidence.

Network Carriers at DSM: American, Delta, and United

Full-service airlines form the backbone of air travel from Des Moines, linking central Iowa to the world through their massive hubs. While they share similar fare structures — you'll typically pay for checked baggage unless you hold elite status or a co-branded credit card — their route maps, operational reliability, and cabin experiences vary meaningfully.

American Airlines

American operates multiple daily departures to Chicago O'Hare (ORD) and Dallas/Fort Worth (DFW). These two hubs unlock more than 350 destinations worldwide. The schedule is designed for connectivity: early morning flights to ORD put you on the first wave of East Coast and European connections, while late-morning and afternoon DFW flights serve the Southwest, Mexico, and South America. American’s AAdvantage program remains a top reason to choose this airline. You can earn miles not just on flights, but through a wide network of shopping portals, dining programs, and a suite of Citi® / Barclays credit cards. Upgrade instruments — systemwide upgrades and 500-mile stickers — provide greater flexibility than many competitors, though availability can be tight during peak business travel. Onboard, all DSM flights offer a two-class cabin with Wi-Fi and streaming entertainment. If your plans involve a lot of Texas, Florida, or international long-haul travel, American’s schedule density is hard to beat.

Delta Air Lines

Delta has built a reputation for operational reliability, and its DSM service reflects that commitment. Nonstop flights to Atlanta (ATL) and Minneapolis/St. Paul (MSP) run year-round, with frequency that allows same-day business trips to the Southeast or Upper Midwest. Atlanta serves as Delta’s primary gateway to Europe, the Caribbean, and South America, while MSP provides smooth connections to Canada and the Pacific Northwest. The SkyMiles program, despite recent shifts toward revenue-based earning, still offers strong value for those who fly frequently on Delta or partner airlines like Air France-KLM and Virgin Atlantic. Medallion status holders also enjoy complimentary upgrades on regional routes, and the airline’s partnership with American Express gives cardholders access to a long list of statement credits and companion certificates. Delta’s DSM flights feature Main Cabin, Comfort+ with extra legroom, and First Class on aircraft equipped with larger regional jets. The airline’s cancellation and standby policies are generally traveler-friendly, especially for elite members, and the Fly Delta app gives robust real-time rebooking options.

United Airlines

United connects Des Moines to Denver (DEN) and Chicago O’Hare (ORD), two hubs with enormous domestic reach and extensive international networks. Denver is particularly valuable for anyone heading to the Mountain West, California, or Hawaii, while ORD anchors United’s transatlantic and Midwest offerings. The MileagePlus program remains one of the industry’s most versatile, with access to Star Alliance partners like Lufthansa, ANA, and Singapore Airlines. Award availability, especially for premium cabin redemptions, is often superior to that of American or Delta, and the Excursionist Perk — a free one-way award segment on select multi-city itineraries — is a unique differentiator. United’s DSM flights generally feature a two-cabin layout with Economy Plus seats that can be purchased or selected at booking for elites and some cardholders. Wi-Fi and in-flight entertainment are standard. For travelers who prioritize flexibility and West Coast access, United’s morning DEN departures and evening returns fit a variety of schedules, and the carrier’s mobile app provides proactive delay and rebooking alerts that reduce terminal stress.

Low-Cost and Ultra-Low-Cost Airlines: Southwest, Allegiant, and Frontier

Not every traveler needs a global network or elite status perks. Southwest, Allegiant, and Frontier cater to different segments of the price-sensitive market, but their approaches to fees, boarding, and schedule reliability diverge significantly. Understanding these differences ensures you don’t end up with sticker shock at the baggage counter.

Southwest Airlines

Southwest’s value proposition is simple: two free checked bags, no change fees, and a personable in-cabin experience. From DSM, the airline serves Denver, St. Louis, and a rotating set of seasonal destinations that often include Orlando, Phoenix, or Las Vegas. Because Southwest doesn’t assign seats, its open boarding process rewards early check-in — a strategy savvy travelers use by setting a reminder exactly 24 hours before departure. Rapid Rewards, the loyalty program, uses a revenue-based earning model and offers a Companion Pass, which allows one person to fly with you for just the taxes and fees on both paid and award tickets. That pass is widely considered one of the most valuable perks in the U.S. airline industry. For Midwestern families, Southwest’s combination of free bags and schedule flexibility often offsets a slightly higher base fare compared to the ultra-low-cost carriers. The schedule can be thinner than network airlines, so check frequency before you commit to a tight connection.

Allegiant Air

Allegiant operates a different playbook: point-to-point leisure routes to small, secondary airports like Orlando/Sanford (SFB) and Punta Gorda/Fort Myers (PGD). Its on-time rate at DSM is consistently among the best — often above 85% — in part because the airline avoids congestion at major hubs. Allegiant’s pricing is unbundled, which means the base fare covers only a seat and a personal item. You’ll pay extra for a carry-on, checked luggage, seat selection, and even a printed boarding pass at the airport. To compound this, Allegiant’s website frequently promotes bundles that can significantly reduce add-on costs if you know what you need upfront. The myAllegiant credit card can soften the fee burden with priority boarding and a statement credit on in-flight purchases, but it’s not a traditional mileage-earning loyalty program. The airline flies less than daily on most routes, so always check the schedule; a delay could mean a multi-day disruption, making travel insurance or a flexible backup plan a smart consideration when booking.

Frontier Airlines

Frontier mirrors Allegiant’s unbundled model but connects DSM to a larger network via its Denver hub. Nonstop flights also serve Orlando (MCO) and, seasonally, cities like Las Vegas, Tampa, or Fort Myers. The airline’s Discount Den membership, an annual subscription, can unlock lower fares for a traveling party, often making it worthwhile for families who book multiple trips a year. Frontier’s FRONTIER Miles program, recently revamped, allows you to earn miles based on fare class and elite status, with a path toward family pooling that few other carriers offer. But fees are aggressive: carry-ons and checked bags are best purchased at booking for the lowest rate, and the personal item sizer at the gate is strictly enforced. Onboard, the slimline seats and optional tray table purchase (yes, you can pre-order snacks and a seat assignment) are designed to keep costs at rock bottom. If you’re comfortable traveling with only a backpack and can be flexible on dates, Frontier can get you to the West Coast or Florida for well under $100 round-trip during sales.

Beyond the Ticket: Using DSM’s Terminal Facilities to Your Advantage

The compact layout of Des Moines International Airport is a strategic asset. Check-in, security, and gates are all within a short walk, and the terminal’s single-level design means you rarely get lost. The DSM official website publishes real-time parking availability for the attached garage and surface lots — a small but valuable detail when you're cutting it close. Inside, the free Wi-Fi is robust enough for video calls, and the abundant charging stations near gate areas let you board with a full battery. Dining options range from pre-security Grab-and-Go markets to sit-down restaurants like Fuel American Grill, where you can enjoy a full breakfast or an Iowa craft beer. Business travelers will appreciate the quiet workstations and semi-private cubicles overlooking the apron. For families, a dedicated nursing suite and a pet relief area mean everyone travels more comfortably. If you need rental car services, counters for Enterprise, Avis, Budget, Hertz, and National are all inside the arrivals hall, and many off-airport agencies provide shuttles. The airport recommends arriving 90 minutes prior to a domestic departure; during peak morning periods, adding an extra 15 minutes can prevent needless anxiety at the TSA checkpoint.

DSM’s route map now covers more than 20 nonstop destinations, with additional seasonal additions popping up during spring break and winter holidays. Some of the busiest corridors include:

  • Chicago O’Hare: Up to nine daily flights combined on American and United.
  • Denver: Service from United, Southwest, and Frontier, giving travelers the choice of hub connectivity or low-cost point-to-point.
  • Atlanta: Delta’s strongest hub, ideal for Southeast, Florida, and international connections.
  • Dallas/Fort Worth: American’s megahub for Texas, Mexico, and South America.
  • Minneapolis/St. Paul: Delta’s northern gateway with easy one-stop access to the Pacific Northwest and Canada.
  • Orlando area: Frontier serves MCO, Allegiant flies to SFB — both put you close to theme parks and convention centers.
  • Las Vegas: Allegiant’s nonstop is popular for weekend getaways.
  • St. Louis: Southwest’s regional bridge to the East Coast.

Seasonal routes to Punta Gorda, Fort Myers, Tampa, and Phoenix appear reliably each year. International nonstops aren’t currently offered, but one-stop connections through Atlanta, Dallas/Fort Worth, or Chicago can land you in Europe, Asia, or the Caribbean with surprising ease. Track the DSM nonstop destinations page for the latest additions, as the airport continues to pursue new service incentives with airlines.

Smart Booking Strategies for Des Moines Flyers

Use Price Tracking and Fare Calendars

Flexibility is the single biggest money saver. Start with Google Flights and enable the “Track Prices” toggle. The tool will email you when fares shift on chosen routes, and its date grid function reveals whether flying a day earlier or later could cut your cost by 20% or more. For ultra-low-cost carriers, also check their native sites: Allegiant and Frontier often run site-specific sales that don’t appear on aggregators. The KAYAK Hacker Fare option can split a round-trip into two one-ways across different airlines, which is especially useful at DSM where mixing Southwest’s free bags on the outbound with a cheap Frontier return might yield a better all-in price than a traditional round-trip.

Factor All-In Costs, Not Just Base Fare

When comparing airlines, build a simple spreadsheet or use an online comparison tool that includes seat selection, one checked bag, and a carry-on. For a family of four, Southwest’s “free bags” can easily wipe out a $50 per ticket advantage from an ultra-low-cost rival. Conversely, a solo traveler with only a backpack might find Frontier’s $39 base fare unbeatable. Also weigh nearby alternative airports: Kansas City International (MCI), about three hours south, often has significantly cheaper transcontinental fares on airlines like Alaska and JetBlue. St. Louis Lambert (STL) and Omaha (OMA) are within driving distance as well, and for a group, the savings may justify the time and parking expense.

Leverage Loyalty Programs and Credit Cards

If you fly from Des Moines more than twice a year, focus your spend on a single network airline’s credit card. The Delta SkyMiles Gold American Express, for example, offers a free first checked bag and priority boarding — meaning on just two round-trips, a family of three recoups the annual fee in baggage savings. United’s Explorer card and American’s AAdvantage Aviator Red offer similar perks, plus a path to early boarding and upgraded seats. For infrequent travelers, co-branded cards from Southwest or Frontier can still be worthwhile for the sign-up bonus if you have a specific trip in mind, but always check that the airline serves your desired route consistently from DSM before committing to a loyalty ecosystem.

Travel Logistics Made Simple: Hotels, Cars, and Backup Plans

Park-Sleep-Fly Packages

Early-morning flights from DSM are less stressful when you spend the night nearby. The Fairfield Inn & Suites Des Moines Airport and Hilton Garden Inn offer park-and-fly packages that include one to two weeks of parking and a shuttle to the terminal, often for less than the cost of long-term parking at the airport. Booking directly through the hotel’s website or calling the property can unlock rates not visible on third-party sites. For those who prefer on-airport parking, the garage is connected to the terminal by a skywalk, and the economy lots are a short shuttle ride away. Real-time occupancy is available on the airport’s parking page.

Car Rental and Ground Transportation

All major rental agencies maintain on-site counters, and returning a vehicle is as simple as parking in the rental lot and walking into the terminal. If you find airport rates too high, consider renting from an off-airport location such as an Avis or Enterprise neighborhood branch; many offer free pickup service to bring you to the counter, though you’ll need to budget extra time. Ride-sharing services like Uber and Lyft have designated pickup zones directly outside baggage claim, and local taxi companies also operate with flat rates to downtown Des Moines.

The Case for Travel Insurance

When flying airlines with limited frequencies — especially Allegiant or seasonal Southwest routes — a single weather delay can cause a missed vacation day or costly alternative flight. A comprehensive travel insurance policy with trip interruption coverage can reimburse you for unexpected hotel and meal costs. Several credit cards offer built-in trip delay protection if you use them to purchase your ticket, but the coverage limits vary widely, so review your card’s benefits guide before assuming protection. For peace of mind, InsureMyTrip and similar sites let you compare policies side by side.

Nearby Airports: When Driving Makes Sense

In central Iowa, a three-hour drive to Kansas City International (MCI) can unlock nonstop flights to Seattle, Boston, New Orleans, and Cancún — routes that from DSM would require a connection. Similarly, St. Louis Lambert (STL) offers robust Southwest service to the East Coast and often lower base fares to Florida. Omaha’s Eppley Airfield (OMA) is just two hours west and sometimes cheaper on West Coast itineraries because of competitive pressure from multiple carriers. Before you commit to driving, calculate the true cost: gas, tolls, off-site parking, and the value of your time. If the per-ticket savings are less than $100, the convenience of flying nonstop from DSM usually wins out. But for a family of five booking peak summer flights, a drive to MCI can sometimes net savings of $300 or more, making it a financially sound move.
