Delta canceled the flight after not enough crew members could be located to operate the plane. Mills was arrested and has been charged with operating a motor vehicle under the influence, alcohol intoxication and terroristic threatening, after she told the captain "you're dead," as she was escorted out of the plane and placed onto a stretcher.
Mills is currently in the Fayette County, KY jail. And yes, apparently "terroristic threatening" is a real crime. Good job, Delta. This regional carrier represents your brand well.
