Sioux Gateway Airport (SUX), also known as Colonel Bud Day Field, is not merely a transport hub but a true local landmark with a unique character. Located at the junction of three states (Iowa, Nebraska, and South Dakota), it offers travellers a cosy alternative to busy hubs, combining rich military history with a famous sense of humour that has turned its IATA code into a recognisable brand. Here, in the heart of the Midwest, modern service sits alongside museum exhibits, and pre-flight procedures take just a matter of minutes.

Features and Advantages of the Airport:
The main advantage of Sioux Gateway is the phenomenal speed of service. Thanks to the compact terminal and low passenger flow, passing through security control (TSA) here rarely takes more than 5–10 minutes, allowing you to arrive at the airport much later than in major cities. Free Wi-Fi is available for passengers, and the car park is within walking distance of the entrance.
The airport takes pride in its past and present. Inside the terminal, there is a historical exhibition dedicated to World War II aviation and the heroic feat of the United 232 flight crew. Furthermore, the administration has skilfully played upon the peculiar airport code (SUX) by launching a line of souvenirs with the slogan "Fly SUX", which can be purchased at the local shop — an excellent way to take home a piece of Iowa's self-irony.
