Amex KrisFlyer Card Reduces Min Spend and Cashback For Singapore Airlines Cashback
American Express has announced changes to the Singapore Airlines cashback benefit offered by the Amex KrisFlyer Credit Card, with the revised benefit taking effect from 19th November 2026.
The cashback amount will be reduced from S$150 to S$100. At the same time, the minimum spending requirement to qualify will also be halved from S$12,000 to S$6,000. The minimum Singapore Airlines flight booking amount will similarly be reduced from S$800 to S$400.

What does this mean for existing cardholders?
For existing cardholders to qualify for the S$150 cashback, they must:
- Accumulate at least S$12,000 in qualifying card spending between 1st July and 18th November 2026 (both dates inclusive).
- Make an eligible Singapore Airlines flight booking of at least S$800 in a single transaction within 6 months of the date they reached S$12,000.
Cardholders who do not reach S$12,000 by 18th November will fall under the new S$100 cashback arrangement instead.
New benefit is equivalent to around 1.56% additional cashback
Amex KrisFlyer Card has been a weak card for a long time and this new benefit doesn’t do much to move the needle in terms of the card’s value proposition.
A cashback of S$100 for essentially S$6,400 of spend (i.e. S$6,000 on any eligible spend and S$400 on Singapore Airlines‚ is equivalent to 1.56% cashback. This is on top of the card’s earn rate, but at 1.1 miles per dollar, the Amex KrisFlyer Card has one of the lowest earn rates around.
It isn’t too difficult to get 4 miles per dollar on your spend, so using Amex KrisFlyer incurs an opportunity cost of 2.9 miles per dollar for most spend. This is not something 1.56% cashback can offset.
Nonetheless, if you have a larger purchase that 4 miles per dollar cards cannot deal well with, Amex KrisFlyer might still be a viable option.
