Des Moines International Airport is small, with only two concourses and a few shops and restaurants. Its diminutive size makes it fantastically breezy to get through, though - you can generally move through check in and security at DSM in under 15 minutes. Most flights leaving out of this airport go through major hubs like Dallas or Chicago, but there's a wide variety of airlines that come in and out of this place. The first 45 minutes of WiFi are free, and its simple, intuitive layout means that any time you spend here before picking up your Des Moines rental car won't be boring. On the first level is the main terminal, where you'll find a food court as well as a gift shop, while the upper level with the concourses has a sit-down restaurant and a grab-and-go food shop.
