American Airlines Flights from Chicago to Sioux Falls

American Airlines on this route

Chicago is a American Airlines hub, so American Airlines typically offers several daily departures on CHI–FSD, with nonstop service where demand supports it and connections through its other hubs otherwise. The nonstop flight time is about 1h 41m.

Fare classes available: Basic Economy, Main Cabin, Main Cabin Extra, Premium Economy / First / Flagship. American does not charge change fees on Main Cabin and above for travel within the US, and on most international itineraries originating in North America. Fare difference applies.

Recorded lows on CHI–FSD start at $432 one-way. That figure comes from cached search data and moves with demand, so treat it as a benchmark for what a good price looks like rather than a guaranteed fare.

Delta Air Lines and United Airlines both operate hubs at one end of this route, so nonstop or single-connection service is usually available, along with American Airlines and Southwest Airlines. Our agents can book any of them and compare fare classes side by side.

Expect roughly 1h 41m nonstop for the 461 miles. On routes this length, basic economy and standard economy often differ by less than a checked-bag fee, so it pays to price the higher fare with the bag included.

When to fly

From the Midwest, the expensive weeks cluster around Thanksgiving, Christmas, and spring break in March; May, early June, September, and October tend to price lowest.

Midweek travel almost always beats weekends on price here. If your dates are flexible by a day or two, tell the agent; shifting a Friday departure to Thursday or a Sunday return to Monday is the single most reliable way to cut the fare.

For domestic travel, booking three to eight weeks ahead usually captures the best price. Inside two weeks, fares climb; more than four months out, airlines have not yet released their cheapest inventory.
