I haven't flown commercially in years, so I'm not up to speed on all of the latest In Flight Entertainment systems available to passengers these days. Can the in-flight chat system be turned off? Can offensive chat posts be deleted? What action (if any) did the flight attendants take?
Is it merely synchronicity that the chat offendee, "Legal expert Jessica Van Meir ...", is an employee of a "... a law firm that specialises in online sexual harassment", or perhaps a clever ploy to generate publicity for her and her employer? Oh wait, I'm sure that would never happen, especially with lawyers in the mix!
Just sayin'.
Cheers,
