IMPROVED: How to transfer Singapore Airlines KrisFlyer miles into Marriott Bonvoy points
This article ran a few weeks ago, in January 2026. However, next week KrisFlyer will improve the transfer rate to Marriott Bonvoy to 4:3. I have therefore updated the article and diverted the old one to this.
Back in the olden days, it was relatively common for airlines to allow you to transfer your miles into hotel programmes. American Airlines was particularly keen.
Then, slowly but surely, a pyramid developed:
- car hire firms would allow transfers to hotels or airlines
- hotels would allow transfers to airlines
- airlines wouldn’t allow transfers to anyone
This is now unravelling. The leader has been ALL Accor (Novotel, Ibis, Mercure, Fairmont etc) which has developed partnerships with large numbers of airlines to convert their miles into hotel points.
Accor doesn’t work with British Airways or Virgin Atlantic but you CAN convert Avios to Accor hotel points by moving them to Qatar Airways Privilege Club and transferring from there.
(It’s a bad deal, of course, but you can do it.)
Other options include Virgin Atlantic (transfer to IHG and Hilton) and Finnair (transfer to Accor). None represent great value compared to redeeming your miles for a flight, but that is hardly surprising – buying hotel points costs the airline real money.
Singapore Airlines KrisFlyer partners with Marriott Bonvoy
A little known option, which launched three years ago, is that you can transfer Singapore Airlines KrisFlyer miles into Marriott Bonvoy hotel points.
You had been able to transfer the other way for years at the standard ‘Marriott to airlines’ transfer rate of 3:1.
The transfer rate from KrisFlyer to Marriott Bonvoy is 4:3.
This is an improved rate from 1st April 2026. The rate was previously 2:1.
You need to transfer a minimum of 3,000 KrisFlyer miles to Marriott, getting you 2,250 Marriott Bonvoy points. The maximum number of Singapore Airlines miles you can transfer has been increased to 250,000 per calendar year.
The small print says that transfers could take up to EIGHT weeks to complete. This isn’t an option if you are desperate to book a hotel.
This is, clearly, not good
Even with the improvement in the transfer rate from 2:1 to 4:3 (effectively 2:1.5) this is not a great deal.
Let’s assume that a KrisFlyer mile is worth 1p for the sake of argument. Our value of a Marriott Bonvoy point is 0.5p. You are trading 2p of Singapore Airlines miles for 0.75p of Marriott Bonvoy points.
So why are we even mentioning this?
There are two reasons why this may be of some use.
First, KrisFlyer has a ‘hard expiry’ policy. Irrespective of what you do, your miles will expire after three years. Clearly something is better than nothing and if you have a handful heading towards expiry then this is a way to get some value.
Secondly, if you have a Star Alliance flight coming up and no interest in collecting Star Alliance miles, this is an option. As long as the flight would earn 3,000 Singapore Airlines miles, you could credit it to KrisFlyer and send the miles to Marriott Bonvoy. Again, it’s better than nothing.
Is there any arbitrage?
No. The loss of value is so huge that there is no merit in, for example, moving American Express Membership Rewards points to KrisFlyer instead of moving them directly to Marriott Bonvoy.
In my case, I have 1,100 orphaned KrisFlyer miles. There is no value in topping those up with Amex points to get to 3,000 because I could send the same number of Amex points directly to Bonvoy and get more. My KrisFlyer miles will sit there until they expire or I can pick up another 1,900 to allow a transfer to Marriott.
There is also a status match and status challenge
Marriott Bonvoy and Singapore Airlines also have a status match and status challenge.
You can find full details in this HfP article but in summary:
Got Marriott Bonvoy elite status?
Marriott Bonvoy Platinum, Titanium and Ambassador members receive a one-off status match to the KrisFlyer Elite Silver tier. You will be upgraded to KrisFlyer Elite Gold if you take four flights on Singapore Airlines within six months of linking your accounts.
Marriott Bonvoy Gold members get nothing automatically but can take part in the status challenge. You will be upgraded to KrisFlyer Elite Silver if you take two flights on Singapore Airlines within six months of linking your accounts.
Elite Silver does not get you lounge access, unfortunately.
Got Singapore Airlines elite status?
Solitaire PPS Club, PPS Club and KrisFlyer Elite Gold members receive a one-off status match to Marriott Bonvoy Gold. This isn’t worth a huge amount but does get you a 2pm check-out if available and bonus points on all Marriott stays.
KrisFlyer Elite Silver members get nothing from Marriott automatically but can take part in a status challenge.
