No, you cannot purchase miles (and if people are offering to sell you points, it's a violation of the Velocity terms as well as AFF, as they would be doing a 'family transfer' and charging you).
If you have a partner/spouse who is eligible, you could pool points to get up to 40,000 (if you both get the card that is) and of course, any other family members could transfer you points.
The Frequent Flyer Concierge team takes the hard work out of finding reward seat availability. Using their expert knowledge and specialised tools, they'll help you book a great trip that maximises the value for your points.
