The sole attendant on a flight operated by a United Airlines regional airline was drunk and slurred a safety speech before passing out, prosecutors and passengers said.

On Thursday, the St. Joseph County Prosecutor's Office in Illinois charged Julianne March, 49, with public intoxication after the Air Wisconsin flight from Chicago to South Bend, Indiana, on August 2, the Belleville News-Democrat reported.

A passenger said March gave an incomplete safety address, staggered into passengers, dropped items, and passed out unbuckled.

Prosecutors said that March acknowledged drinking two vodka "shooters" before work and that her blood-alcohol content was .204, the News-Democrat reported.

An attendant on an August 2 flight operated by a United Airlines regional airline was intoxicated on duty, slurring through an incomplete safety speech before passing out, prosecutors and passengers said.

The St. Joseph County Prosecutor's Office in Illinois on Thursday charged Julianne March, 49, with public intoxication, the Belleville News-Democrat reported, citing an affidavit.

The police met with March immediately after the Air Wisconsin aircraft landed in South Bend, Indiana, from Chicago's O'Hare International Airport, the report said.

A passenger, Aaron Scherb, told the News-Democrat and ABC News that March, the sole attendant on the flight, slurred her in-flight safety speech and stopped after 10 seconds, ignored a call on the plane's internal telephone, dropped things, bumped into passengers, and passed out in her seat unbuckled.

After the police took March off the plane in South Bend, they asked her what city she was in, and she replied "Chicago," prosecutors said, according to the News-Democrat.

They said a breathalyzer test showed that March's blood-alcohol content was .204, five times the legal limit for flight attendants, ABC News reported.

Citing the affidavit, the News-Democrat described March as having "bloodshot eyes, slurred speech, poor balance and the smell of alcohol on her breath."

A St. Joseph County Prosecutor's Office spokeswoman told the News-Democrat that March could face six months in jail if found guilty.

The affidavit said March had "endangered the life of another person ... the passengers on the flight," the newspaper said.

Air Wisconsin told ABC News that March was no longer employed with the airline.

United Airlines did not immediately respond to Business Insider's request for comment.
