American Express has a new bonus miles earning offer for its KrisFlyer co-brand cardholders between now and early March 2022, offering an additional 2 miles per dollar on top of your card’s usual earn rate when you make payments to over 280 retail stores via the Singapore Airlines Kris+ app.
The deal is limited to the first 8,000 successful enrolments, so it’s worth saving this offer to your card now if you wish to take advantage.

The promotion runs from 3rd December 2021 to 2nd March 2022.
Bonus KrisFlyer miles for Kris+ transactions
Simply find the offer on the Amex mobile app and save it to your card, then spend in-app at Kris+ merchants using your Amex Singapore Airlines co-brand card.
The card will have to be saved in your mobile wallet to be used on Kris+ (this is now the only way to pay and therefore earn miles through the Kris+ app anyway).
Here are the revised earn rates applicable for Kris+ spend during the promotion.

Sadly the deal is capped at only 400 bonus KrisFlyer miles per card, which is equivalent to just S$200 cumulative Kris+ spend during the promotion period.
Bonus miles will credit directly to your KrisFlyer account, usually within five working days from the transaction, however it can take up to 90 days from the end of the promotion period in some cases (i.e. until 31st May 2022).

Provided the bonus miles credit before 28th February 2022, you’ll also earn additional Elite miles or PPS Value to help you retain your KrisFlyer or PPS Club membership tier, or climb the ladder to the next tier, as part of SIA’s ‘Unlock Status Credits Without Flying’ campaign.
Kris+ spend is also included in that promotion, so there’s some ‘double-dipping’ here.

Kris+ up to 9 mpd earning
This offer stacks quite nicely with an extended bumper promotion from Kris+, offering up to 9 mpd at over 280 island-wide merchants through the app itself, on top of the 3.1 to 3.3 mpd you’ll pick up through your co-brand card as part of this Amex deal.
That means a total earn rate of up to 12.3 mpd at selected merchants – not to be sniffed at!
Don’t forget – transfer straight to KrisFlyer miles
While your 3.1 to 3.3 mpd earning though this Amex promotion will credit directly to your KrisFlyer account, remember that you’ll also earn KrisPay miles through the Kris+ app (up to 9 mpd) for your purchase too.
These KrisPay miles can only be transferred to your KrisFlyer account within 7 days of the transaction. To do so, simply tap on the “Transfer to KrisFlyer” button which will appear on the miles earned confirmation screen or transaction details screen.

You can do so later (within 7 days), but why wait?
Remember that KrisPay miles earned per transaction can only be transferred to your account in their entirety. If you earned 100 KrisPay miles from a single Kris+ transaction, for example, the full 100 KrisPay miles must be transferred to your KrisFlyer account. If you have already spent some of your KrisPay miles earned, a partial transfer option is not available.
We therefore recommend transferring to KrisFlyer immediately following any Kris+ earning transaction, in case you either forget or make a mistake later.
Better earning rates for Kris+
Many 4 mpd cards on the market in Singapore earn at their top bonus rate for Kris+ transactions, in selected Merchant Category Codes (MCCs).
That’s a little complicated, because the payment you make in-app with those cards will tag under the merchant’s MCC (not a generic Kris+ one), so you’ll need to be confident it qualifies prior to your purchase, unlike with this Amex deal where all Kris+ transactions will be bonus-eligible for those who successfully register.
Here’s how some of these cards earn for Kris+ payments, within their monthly spend caps.

In many cases you’ll want to ensure you’re exhausting your 4 mpd options for eligible Kris+ spend before using this Amex offer, though the latter could be quite useful if you use up your bonus caps on these cards already.
Summary
Not the most generous spend cap at only S$200 with this Amex / Kris+ offer, but that should still mean a relatively easy 400 bonus KrisFlyer miles if you have some Kris+ spend coming up between now and early March next year.
The deal isn’t as good as you’ll get using many existing 4 mpd cards with the right merchant, but it is simple (any Kris+ merchant earns the Amex bonus) and provides an additional cap for big spenders.
Do check out the latest Kris+ merchants via the app if you haven’t recently, with many new retailers now included on the nearly 300-strong list, including Anti:dote at the Fairmont, SKAI at the Swissotel and LeVeL33 bar and restaurant, with up to 9 mpd on offer even before this Amex bonus.
