Nearby Saint Louis is 238 miles to the East; you can expect the flight to take roughly an hour to complete, as this includes any potential departure delays. Both cities are major metropolises; large and spread out, there is much to see and do in St. Louis. The weather, nightlife scene, and city skylines are comparable. Flights from Kansas City to St. Louis are available via Delta, United, Continental Airlines, US Airways, and American Airlines.

Departing Kansas City International

Initially named Mid-Continent, Kansas City International is the departure city’s main airport located 15 miles to the northwest of its downtown area. It transports over 10 million foreign and domestic passengers each year, and has been ranked among the top five on J.D. Power and Associates’ North America Airport Satisfaction Studies multiple times.

The airport also received the highest rating of any medium-sized airport, so that says a lot about its passenger features, amenities, and quality of customer service. Delta Air Lines and Southwest Airlines are the facility’s largest carriers.

Kansas City International spans 10,000 acres and has three runways. It underwent a major $260 million terminal upgrade in 2004, a project that included the addition of stylish and aesthetically appealing blue terrazzo floors in each of its three terminals!
