In a letter to executives of the Alaska airline, she explained and said that she was extremely uncomfortable with a man sitting near to her, he constantly made sexually explicit and made comments to her.
When pressed on the issue, flight attendants told Zuckerberg, who stressed that she was "extremely uncomfortable", that she could move to a middle seat at the back of the flight.
"Why should I have to move?" she said.
Flight attendants told Zuckerberg the passenger was a frequent flyer with the airline, and while they have had to talk to him about his behavior in the past, she shouldn't take it personally because he "just doesn't have a filter". The flight attendants told me he was a frequent flier, brushed off his behavior & kept giving him drinks.
During the three-hour flight, the man was given multiple alcoholic drinks, she said, and continued to harass her the entire time. She claims the staff allowed a fellow first-class passenger to engage in a lengthy alcohol-fueled, generally gross rant in which he asked her if she "fantasized" about her female colleague, rated women's bodies onboard the flight, talked about touching himself, and complained that "millennial women just aren't willing to give some booty to get a job anymore".
Some people thanked her for being courageous enough to speak out and others offered their sympathy.
Shortly after tweeting her complaint, Zuckerberg followed up to say the airline had reached out to inform her it had suspended the other passenger's privileges and that it is investigating the matter.
"While it should never have happened in the first place, I am thankful that they are taking the situation seriously", she wrote in an update to her original Facebook post.
"The safety and well-being of our guests and employees is our number one priority", Schneider said in the post.
"What Randi Zuckerberg shared with us is very disturbing", Lane said, later adding: "As a company, we have zero tolerance for any type of sexual misconduct that creates an unsafe environment for our guests and crew members".
In the recent times, a number of cases of harassment were faced by flight passengers on board but majority are either brushed aside by authorities or dissolve with time.
