The two women, who were traveling together, began fighting and hurling loud expletives at each other in front of shocked fellow passengers, according to KLAS-TV/Las Vegas. At one point, one of the women reportedly struck a male passenger on or near his head.

As of Thursday morning, neither woman has been identified.

A witness told KLAS ​that a flight attendant tried several times to stop the fight before finally separating the women and moving one to a different seat. But they continued shouting expletives at each other after being separated, the witness said.

The cellphone video below was uploaded by the news station:

“It was fairly disruptive, so passengers began to tell them to shut up because their behavior was escalating,” the witness told the news station.

“Just get your s*** together so we can get home,” a passenger is heard saying in the video.

Another passenger admonished the women to “get some class.”

​Fellow passengers cheered when the two women were forced to deplane at Denver International Airport, where they were met at the gate by Denver police officers.

​”You’re gonna go to jail … who are you trying to impress?” one passenger said.

Causing a disturbance on an airplane is a federal crime that can subject offenders to criminal charges, though it was not immediately clear whether either of these women faces any.

Flight 2143 left Philadelphia at 10:30 p.m. E.T. and was scheduled to arrive in Vegas at 10:30 p.m. PT. To Frontier s credit, the flight was only an hour late.
