American Airlines has suspended a flight attendant who allegedly hit a woman with a pram and then challenged another passenger to a fight.

A fellow passenger who filmed the aftermath of the incident says the mother had her pram "violently" taken from her before being struck.

In the footage, the woman can be seen crying while holding her child as other airline employees attempt to calm the situation.

The clash then escalates when another passenger confronts the flight attendant.

"You try that with me and I'll knock you flat," he can be heard saying.

The flight attendant then taunts him, saying: "Hit me! Come on, bring it on."

The video was posted to Facebook and captioned: "AA Flight attendant violently took a stroller from a lady with her baby on my flight, hitting her and just missing the baby. Then he tried to fight a passenger who stood up for her."

According to ABC News, a spokesperson for the airline says the dispute was over whether or not the pram should be allowed on the flight.

American Airlines is reportedly investigating the incident which took place on Friday's Flight 591 from San Francisco to Dallas. The employee involved in the altercation has since been suspended.

In a statement, the company said: "We are deeply sorry for the pain we have caused this passenger and her family and to any other customers affected by the incident."

The clash comes just weeks after United Airlines faced backlash for forcibly dragging a man off a plane after it was overbooked.
