NEW: Transfer Singapore Airlines KrisFlyer miles into Marriott Bonvoy points

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 Accor Live Limitless (Novotel, Ibis, Mercure, Fairmont etc) which has developed partnerships with huge 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 points by moving them to Qatar 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 various schemes including IHG). Again, 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 is now starting hotel transfers
In a surprising development, you can now transfer Singapore Airlines KrisFlyer miles into Marriott Bonvoy hotel points.
You have 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 2:1.
You need to transfer a minimum of 3,000 KrisFlyer miles to Marriott, getting you 1,500 Marriott Bonvoy points. The maximum number of Singapore Airlines miles you can transfer is 180,000 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 but you could take advantage of Marriott’s ‘Points Advance’ feature to book now and earn the points later.

This is, clearly, awful
Let’s assume that a KrisFlyer mile is worth 1p for the sake of argument. You are trading 2p of Singapore Airlines miles for 0.5p 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 an option.
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?
There is no arbitrage here as far as I can tell versus any other scheme. 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 that 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 keep sitting there until they expire or I can pick up another 1,900 to allow a transfer to Marriott.
