I read an interesting article today about a social influencer who says she got a pre approval from an airline for an upgrade to business class on a long haul flight to NYK. When she showed the email at the check in desk they said it was fake and she was eventually banned from flying with them. Afterwards the airline asked her to send them the actual email she sent and received because they have no records on their email sever and the person's name on the email said he has never sent the email, she ignored them and said she would only communicate via her lawyer in future. Needless to say she didn't have a lawyer, and now she is much more famous/infamous than before ^_^
