The scene unfolded on Sunday as the plane was about to leave Miami International Airport on its way to Los Angeles.
Video shot by a passenger shows the woman, identified by police as Tiffany McLemore, striking her husband with the laptop after an expletive-filled argument between the couple.
In the video, the woman can be heard swearing at her husband while a group of flight attendants try to contain the situation, with one pointing out to McLemore that a young child was seated behind the couple.
“You’re out of control,” the husband told his wife before attendants asked him to move to another seat. As he was walking down the aisle, his wife appears to hit him with the laptop.
