From 1 November 2021 any balances over $50,000 will no longer earn Qantas Points. You can still earn 0.3 Qantas Points per $100 each day for any balance under this cap.
Wonder if I can open multiple transaction accounts to spread balance and link them all to the same QFF account.
Really - where did you see this? If this is the case, I'm dropping the account.
