And given that the family got the press involved, for a BNE-MEL flight, my natural bias doesn't lean towards them.
rather than whinging to the media.
This assumes that the family got the media/press involved. My take on this was that yes the family whinged to "the media", if including the all encompassing term of "social" media. It seemed to me that this was publicly posted on QF's facebook page and then picked up by the writer of the article. Given the quotes the writer used were directly from the facebook rant, it would seem to me that the writer didn't even speak to the family, and the family didn't get the "traditional media"/press directly involved.
This is not the first time I've seen people on AFF doubting the sincerity of others because they got the press involved, when in reality it would seem the press got themselves involved. FB and twitter are very easy sources for potential stories of interest, and very quick to get out as a story.
