I have done the exercise on whether it is worth transferring the points or not. If someone could check my calcs here.
I have assumed a $100 Myer gift voucher is the reward in this example for 16950 from Altitude or 13500 with Velocity, and only using Altitude as the originating supplier of the points.
If my altitude account has 176978 points, and I transfer them to Velocity I get 88,250 Velocity points + bonus of 13237 = 101487 Velocity points.
If I use my 176978 altitude points with Altitude to by the $100 myer gift cards I will get 10.44 Myer cards.
If I use my newly acquired balance of 101487 Velocity points, I will only be able to get 7.51 $100 Myer cards.
Now whether redeeming for gift cards is a good use of points or not is another argument.
Can others confirm if my thinking is correct here, that in this example I am best to leave my points where they are if my intention is to buy myer gift cards?
I guess the same exercise can be applied to flights etc, but I wonder how many people (if my math is correct), don't consider this and end up costing themselves?
