Probably the worst airline there is, they don’t know how to be nice, they will threaten to kick you off plane for having to use the bathroom after being on plane for hours without getting sprayed off, or anything worked on, they also don’t have their staffing or anything together in Rapid City SD as I waited 4 hours on a plane there and 12 in the Denver airport, definitely would not recommend United Airlines, Rapid City Regional Airport or Denver International, better off taking 3 flights to avoid lowsy Denver airport
