United Airlines Investigating Allegedly 'Drunk or Stoned' Flight Attendant Who 'Terrified' Passengers

United Airlines is investigating claims that a flight attendant on one of its planes was belligerently "drunk or stoned" during a flight from Denver, Colorado, to Williston, North Dakota, on Thursday.

In a statement to Newsweek, the airline said it was aware of the incident. The flight in question was a Trans States Airlines flight, one of United's regional service providers.

"As a gesture of goodwill, we have compensated all customers aboard the flight and we apologize for any inconvenience or distress this may have caused," United said in a statement to Newsweek. "The safety of our customers and crew aboard all United and Trans States flights is a top priority."

At least one passenger tweeted to United about the incident. According to passenger Erika Gorman, the attendant appeared either "drunk or stoned" and made what was supposed to be a routine flight "terrifying." Gorman said she spoke to the pilot and told him "they had an out of control attendant."

At one point, the flight attendant allegedly told passengers "if your seat belt isn't tight, you fucked up." Police officers and an ambulance were waiting when the plane landed at its destination, according to Gorman.

The passenger also tweeted images of the suspected flight attendant, which have since been deleted.

United Airlines quickly responded to the passenger and said it was "looking into" the "disturbing" claims.

From a public relations standpoint, it's been a bumpy few months for United. On Wednesday, the company revised its pet policy after a 9-month-old dog died in one of its overhead luggage bins. According to the dog owner, she was forced to put the dog into the bin.

On Thursday, the airline announced that it had hired the Obama administration press secretary Josh Earnest as its new spokesperson.
