I am looking for some advice on how to get the most out of my CBA diamond rewards card. My main goal is to use the points to upgrade flights. Or if I should change rewards card to another bank such as ANZ. My partner has a supplementary card and we basically use the cards for everything. I have read some reviews and the CBA diamond rewards doesn’t get much of a rap. What is stopping me from changing cards is that I only pay $119 per year, as opposed to the normal $349.
Additionally should I continue earning CBA rewards points or convert them to Velocity or Qantas points?
