Convert Marriott Bonvoy Points to Singapore Airlines Miles With a 20% Bonus [Until March 31]

Time is short if you want to take advantage of this offer, but you can convert Marriott Bonvoy points to Singapore Airlines KrisFlyer miles with a 20% conversion bonus through March 31, 2025.

For those unaware, you can convert Marriott Bonvoy hotel points into airline miles with dozens of participating airlines, and Singapore Airlines is offering a 20% boost on these conversions for a limited time. With the improved transfer rate, you can turn 3,000 hotel points into 1,800 airline miles.

Does it make sense to use this transfer bonus? Let’s take a look.

Marriott Bonvoy to Singapore Airlines KrisFlyer Transfer Bonus Details

Marriott Bonvoy partners with dozens of airlines, allowing you to convert your hotel points into airline miles — typically at a 3:1 ratio. Normally, converting your Marriott Bonvoy points to Singapore Airlines KrisFlyer miles means turning 3,000 hotel points into 1,500 airline miles.

However, through March 31, 2025, you can receive a 20% bonus on transfers, resulting in a 3,000:1,800 transfer ratio. Conversions are available here, and you’ll first need to link your accounts before you can make transfers.

You must convert a minimum of 3,000 miles, and you can receive a maximum of 180,000 KrisFlyer miles from conversions in a calendar year.

This offer ends at 11:59 p.m. on March 31, 2025, in Singapore. That’s 11:59 a.m. ET on March 31 in the U.S.

Is It Worth It?

We value Marriott Bonvoy points at 0.7 cents each and KrisFlyer miles at 1.35 cents each. Using those numbers, 3,000 Marriott points are worth $21, while 1,500 KrisFlyer miles are worth $20.25. During normal times, you’re losing value on these conversions — unless you’re redeeming your KrisFlyer miles at above-average value or simply have no use for your Marriott Bonvoy points.

With the 20% transfer bonus from Marriott Bonvoy to KrisFlyer, however, you can trade $21 worth of hotel points for $24.30 worth of airline miles. That math is moving in the right direction.

Even still, this won’t make sense for everyone. If you’re interested in utilizing this bonus, ensure you have a plan for how to use your KrisFlyer miles, and be sure the award seats you want are available before initiating a transfer. It can’t be undone if you realize the seats you want aren’t available.

Final Thoughts

Through March 31, you can receive a 20% bonus on points transfers from Marriott Bonvoy to Singapore Airlines KrisFlyer. This bonus won’t make sense for everyone. For those who have Marriott Bonvoy points they don’t intend to use for hotels, however, this could be a good bonus to jump on before it disappears.
