a billionaire former Welsh airline owner
This is just fantasy. I know the gentleman in question from an airline viewpoint probably about as well as anyone does, and he is certainly NOT a billionaire. Also, I do not think for a single second that he is interested in losing another shedload of money on the airline business.
The "Wales Air Network fraternity" would do well not to speculate wildly like this, it does little for their reputation.
