Sioux Gateway Airport

Sioux Gateway Airport, officially Sioux Gateway/Brigadier General Bud Day Field, traces its roots back to the 1930s and today operates a single terminal that handles regional traffic for northwest Iowa and nearby Nebraska and Minnesota. Compact but important for local travel, the airport sits about 6 miles from downtown Sioux City and is accessible by car, rental shuttles, taxis, rideshare and local bus connections, making city access straightforward. It’s generally considered an affordable option compared with larger hubs—parking and fees are modest and regional fares are often competitive, though limited service can affect prices. Not a major hub, the field is primarily served by regional affiliates operating for larger carriers (American/United regional partners) and occasional low-cost or seasonal flights.
