The short hop between Iowa's capital and Chicago's south-side airport is one of the Midwest's most practical connections, whether you're heading to the Windy City for business, a weekend getaway, or an onward international connection. Flights from DSM to MDW typically clock in at just over an hour in the air, making this one of the quicker regional routes you'll find in the central United States.
Southwest Airlines is the dominant carrier on this corridor, operating Boeing 737 aircraft with its signature open-seating policy and two free checked bags. The direct service is convenient, though schedules can vary seasonally, and travelers occasionally opt for one-stop itineraries through hubs like Denver or Baltimore when timing doesn't align. Des Moines International Airport is refreshingly easy to navigate, with short security lines and a compact layout that means you rarely need to arrive more than 90 minutes early. Midway, while busier, remains far less overwhelming than O'Hare and sits closer to downtown Chicago via the CTA Orange Line.
The best time to make this journey depends on your priorities. Late spring through early fall offers the smoothest flying conditions, with June and September being particularly pleasant for exploring Chicago's lakefront, festivals, and outdoor dining scene. Winter travel brings the risk of weather delays, as both airports occasionally see significant snow, ice, and the operational ripples that follow. If you must fly between December and February, morning departures tend to be more reliable than evening ones, since cascading delays worsen as the day progresses.
Fares on the Des Moines to Midway route are generally reasonable given the distance, and booking three to six weeks ahead usually yields the most flexibility. Tuesday and Wednesday departures often prove less crowded than Monday morning or Friday afternoon flights, which fill quickly with business travelers. Frequent flyers appreciate the route's reliability and the fact that Midway's proximity to the Loop means you can be sipping deep-dish pizza in Greektown or checking into a River North hotel within 45 minutes of landing.
For first-time flyers on this pairing, a few practical tips help. Pack layers, since Chicago weather can shift dramatically from what you left in Iowa. Download the Southwest app for mobile boarding passes, and consider EarlyBird check-in if you have a preferred seat in mind. The flight itself is short enough that a book, a podcast, or a quick nap will get you through comfortably, with just enough time for the crew to serve a drink before beginning descent over Lake Michigan.
