The video appears to show a passenger jump up from her seat and start punching the flight attendant in the face, while the passengers nearby try to pull the attacker down. The brawl is stopped by a man who forcefully intercedes, shouting, “Sit down, lady … don’t you dare touch her!”

It seems that the “freakout” was due to the unruly passenger ignoring a number of airline regulations and refusing to put up her tray table in the upright position before landing.

“So, now she’s bleeding everywhere in the back looking at us and this lady who was hit went back to her seat wearing a mask — nothing happened, it seems like,” Taro Arai, the passenger on the Sunday flight who took pictures of the incident, “I’m like huh, woah, I mean, she was so strong she could knock me out.”

“This past weekend, one of our Flight Attendants was seriously assaulted, resulting in injuries to the face and a loss of two teeth,” Lyn Montgomery, president of a local Transport Workers Union (TWU), wrote in a Monday letter to Southwest Airlines CEO and Chairman Gary Kelly.
