(Targeted maybe) This might help some, just got the email from Amex. Personally I transfer to Krisflyer for Bus Class redemptions (been saving for a while)
Your Membership Rewards points are now worth 50% more when you cover any of your eligible Card purchases with points.
Whether it’s your next flight, a boutique hotel or a day trip with friends – choose to cover any of your eligible purchases with your Membership Rewards points up until 30 December 2022 and get 50% more value (minimum redemption amount is 1,000 points).
Works out to be $7.50 per 1000 points.
Example: 20,000 points was worth $100, now worth $150.
Waiting for Amex to KrisFlyer 20% transfer bonus. There was one December last year.
