American Airlines has removed an employee from duty after an ugly clash over a baby's pram in San Francisco.
A passenger who uploaded video of the aftermath of the incident said a mother had been struck with the pram as it was forcibly removed by the employee.
The video shows the employee saying, "Hit me! Come on, bring it on!", when challenged by another male passenger.
American Airlines said it was "deeply sorry for the pain we have caused" the woman passenger and her family.
The incident follows another high‑profile clash on a United Airlines plane two weeks ago, when a passenger was violently removed from an overbooked flight.
