Has anyone 'mastered' the art of using 'Virgin's' frequent flyer airmiles to use towards the cost of a flight, or to 'upgrade' a flight? Is their airmiles program just one big con?. I tried ringing their call centre, I've spent a very long time online, using every date there is, and I have not been able to find a date for this year or next, when flights are available. My wife and I wanted to use our airmiles to 'upgrade' from economy to fly to Las Vegas, there appears to be no way that they will allow this to happen - and they don't seem to care!!
