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.
According to her complain, Flight attendants offered Zuckerberg to move her to a seat at the back of the plane. Zuckerberg also claims he "rated and commented on the women's bodies boarding the aircraft as they walked by us".
Offended by the attendants' offer of moving to another seat, Zuckerberg wrote, "Which I nearly did until I realised. why should I have to move?" She wrote that she was furious with the airline for "knowingly and willingly providing this man with a platform to harass women".
Zuckerberg further asserted that when she brought this to the notice of the flight attendants, they told her that this guy was a frequent flyer and that she should just ignore him. I guess his $ means more than our safety? She was asked if she had sexual fantasies about her travel partner by the man next to her, who continued to make vulgar comments as other female passengers got on the flight.
Staff told the pair that the man, who frequently flew the same Alaska Airlines route, had demonstrated similar "behavior in the past, but oh well, don't take it personally, this guy just doesn't have a filter".
Some people thanked her for being fearless enough to speak out and others offered their sympathy.
Zuckerberg wrote a lengthy email to the airline's leadership after leaving a flight feeling "disgusted" and "degraded." .
Alaska Airlines is investigating a sexual harassment claim by Randi Zuckerberg, a Silicon Valley executive and sister of Facebook Chief Executive Mark Zuckerberg.
Bobbie Egan continued: "The safety and well-being of our guests is our number one priority".
The airline said in part: "We want our guests to feel safe".
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.
