The point is that what can kill an airline dead is loss of confidence = advance bookings fall off = cash flow not what it was = creditors and suppliers start asking for payment upfront = bank starts calling in long term lending = administrators called in on what was a healthy business until the whispers were planted.
One very good way to start the ball rolling is a question like the one at the top of this thread.
My instinctive reaction to that kind of question, on this and other websites, is to wonder on which airline's behalf it has been placed.
MoL does exactly the same thing for exactly the same purpose, although publicly and openly, when he announces that "a lot of airlines are going to fail" or words to that effect, and hints at who they might be. And the press fall for it. And it succeeds....look at the list of victims.
It's all designed to kill by whisper. And that's why when questions like the one posed are placed on pprune, the best thing is to ignore them totally.
Rant over.
