American Airlines says flight attendant "removed from duty"

(CNN) American Airlines is investigating after a video surfaced on social media showing a confrontation between a passenger and a flight attendant aboard one of its flights.

The video, filmed by another passenger Friday, appears to be the aftermath of an incident during boarding of a flight from San Francisco to Dallas. It does not show what happened beforehand.

The incident comes two weeks after a United Airlines passenger was dragged from his seat and off a plane by Chicago aviation police. United was widely criticized on social media and by industry professionals for the conflicting statements it put out afterward, initially siding with its employees and appearing to blame the passenger.

Flight attendant: 'Hit me, hit me'

The video of the American Airlines encounter starts off with a woman sobbing as she holds a baby.
