Passengers aboard a flight headed to North Dakota on Thursday afternoon are being refunded after they were forced to deal with a drunk flight attendant.

According to passenger Erika Gorman, the unnamed flight attendant used profanity while going over the safety instructions, telling passengers: 'If your seatbelt isn't tight, you f***ed up'. The air stewardess was then filmed getting up in a passenger's face.

Gorman tweeted: 'Thanks United, for a terrifying flight! Drunk or stoned stewardess endangered everybody's lives.

'I had to go to the cockpit and call the pilot and tell him they had an out of control attendant. The cops and an ambulance were waiting for her when we landed.'
