Video shows two passengers fighting, apparently over seat assignments, on a flight from Las Vegas to Charlotte, N.C. on Monday.
Fellow passengers react in shock as they watch punches being thrown, along with hair pulling.
The man who recorded the video says the police were called and the woman in pink got off the plane.
No comment yet from American Airlines.
This is not the first time this year that things have gotten tense while on board a flight. In February, a video went viral of a confrontation between two passengers over reclining their seats.
