SkyWest Airlines (self-handled United Express EAS station)
SkyWest operates the Essential Air Service United Express flights from SUX to Chicago O'Hare and Denver and appears to self-handle the station: the airport's own site lists no third-party ground/passenger handler, and SkyWest has posted Airport/Cross-Utilized Agent and Cross-Utilized Supervisor openings for Sioux City IA, consistent with company-employed ticket/gate/ramp staff rather than an outsourced handler.
