Update 11/8/22: According to OMaaT it looks like this card will launch in Australia. No sign up bonus and low earning rates unfortunately.
Bloomberg is reporting that Star Alliance plans to launch a credit card and points will be redeemable at any of the 26 partner airlines. It’s unclear what financial institution will issue the credit card. It will be interesting to see what the specifics of the card are, as I imagine airlines such as United will be unhappy to give up market share to a Star Alliance card (as will partners such as Chase).
