United Express (operated by SkyWest Airlines)
SkyWest Airlines operates the DOT Essential Air Service route to Chicago O'Hare (ORD) as United Express, resumed December 2024 with roughly 12 round trips per week; route and carrier are confirmed by DOT/airport announcements. Below-wing ramp and baggage handling is likely self-performed by SkyWest's own locally hired airport agents, consistent with SkyWest's typical staffing model at comparably small single-carrier EAS stations, but a direct EAU-specific statement confirming self-handling (versus contracting the FBO) was not found and this detail should be treated as an inference, not a confirmed fact.
