Drunk man facing federal charges after allegedly assaulting a woman and urinating on seat aboard Frontier flight

A drunk Frontier Airlines passenger allegedly groped a woman before urinating on the seat in front of him.

A man has been arrested after allegedly groping a woman and urinating in his seat on a Frontier Airlines flight from Denver to Charleston, South Carolina.

Fellow travellers claim Michael Allen Haag downed two double vodkas on the Frontier flight before making unwelcome advances towards a female passenger.

Speaking to FOX 31, a witness identified only as Emily, said: “I hear a woman scream, ‘if this man f*****g touches me one more time, I’ll f*****g kill him’.”

Haag is alleged to have then groped another woman before flight attendants moved him to an empty row of seats at the back of the plane.

It was here Haag began urinating on the seat in front of him.

“And I scream, ‘He’s f*****g peeing. He’s peeing. Oh my God.’ And the flight attendant doesn’t even acknowledge him at first. [The attendant] acknowledges me and says you need to calm down and stop cursing,” Emily said.

Haag was arrested when the plane arrived at Charleston International Airport.

He has been charged with interference with flight crew members, a felony, and indecent exposure on an aircraft.

A Frontier Airlines spokesman told CBS Denver: “The safety and security of our passengers is our top priority at Frontier.

“We have been made aware of this situation and are working with the appropriate authorities.”
