Singapore Airlines KrisFlyer miles expire at the end of the month, 36 months after they are earned, and account activity does not extend their validity.
Most KrisFlyer miles follow a fixed expiration schedule, although elite members and certain promotions may have different rules. Here’s how KrisFlyer mileage expiration works — and what options you have to extend or use your miles before they expire.
Singapore KrisFlyer Mileage Expiration Policy
KrisFlyer miles generally expire at the end of the month, 36 months after the month they were earned. Unlike many airline programs, earning or redeeming miles does not reset the expiration clock. Per Singapore Airlines’ terms and conditions:
“KrisFlyer Basic, KrisFlyer Elite Silver and KrisFlyer Elite Gold members only: a member’s KrisFlyer miles will expire after three years (or one year for KrisFlyer miles received from contests) at 23:59 hours Singapore time (GMT +08:00 hours) on the last day of the equivalent month in which they were earned. For example, KrisFlyer miles credited to a member’s KrisFlyer account in July 2017 will expire at 23:59 hours Singapore time (GMT +08:00 hours) on 31 July 2020”
For example, miles earned in July 2023 will expire on July 31, 2026.
Exceptions to KrisFlyer mileage expiration
Most KrisFlyer members are subject to the 36-month expiration rule. However, miles don't expire for PPS Club and Solitaire PPS Club members. If you lose PPS status, your miles revert to the standard 36-month expiration policy.

KrisFlyer Account Expiration Rules
Even worse, your KrisFlyer account will expire 45 months after your last mile-earning date — or 24 months after enrollment if you don't make a qualifying transaction. Here's how Singapore Airlines puts it:
Your KrisFlyer account will remain valid for 45 months from the end of the month of your last earning transaction. Your account will also expire if you don’t make a qualifying transaction within 24 months of your enrolment as a KrisFlyer member.
How to Extend KrisFlyer Miles
While you cannot reset your expiration date through activity, KrisFlyer does offer a paid extension option. You can pay $12 (or 1,200 miles) to extend up to 10,000 miles. The length of the extension depends on your status:
- Standard members: 6 months
- KrisFlyer Elite Silver and Gold members: 12 months
This extension must be requested before your miles expire.
To extend your miles validity, log in to your KrisFlyer account and navigate to Miles > Miles Validity.
Historically, you could book an award with your miles, change the date, and then cancel and redeposit your miles for a fee to reset the clock on those miles. This avenue is no longer available, however. Any miles that would have expired will be lost and will not be redeposited.
How to Use KrisFlyer Miles Before They Expire
Since KrisFlyer miles expire on a fixed schedule, the best way to avoid losing them is to plan redemptions before they expire. You can use KrisFlyer miles for:
- Award flights with Singapore Airlines
- Flights with Star Alliance partners
- Upgrades on eligible fares
- Select partner redemptions
If you’re close to an award, you can also top off your balance using transferable points.
Boosting Your KrisFlyer Miles Balance
KrisFlyer is a transfer partner of multiple major rewards programs, making it easy to top off your balance if you are a few points shy of a redemption.
This flexibility makes Singapore KrisFlyer an ideal program for consolidating small point balances into a single balance for your next redemption.

Other Ways to Earn Singapore KrisFlyer Miles
Earning Singapore KrisFlyer miles is relatively straightforward. You can earn miles in any of the following ways:
- Fly with Singapore or any of its Star Alliance members, including Lufthansa and Avianca. You can also earn miles when flying Scoot, JetBlue, Alaska Airlines, and more.
- Stay at hotels, including IHG, Accor, and Hilton.
- Rent a car from Avis, Budget, or other partners.
- Shop around the world, including at the Bicester Village Shopping Collection.
If you are based in Asia, there is a much more comprehensive range of options for you to earn KrisFlyer miles, including multiple co-branded credit cards in various countries.

- Bottom Line
I have 30k points that are set to expire in Dec 2024 and 130k in Feb 2025. If I book award tickets (for Sep 2025) now, will those 160k points remain visible to me on SQ’s miles validity chart, even though the miles have been applied to a ticket? Or will those miles disappear from the validity table once I “buy” award tickets with them? If they would disappear from the table, then it seems to me that I must pay to extend their validity before I book the award tickets. Otherwise, if I don’t extend them first, and I cancel my award after Dec 2024 or Feb 2025, the points will have expired and will no longer be usable.
I don’t have direct experience with expiring SQ miles. But typically loyalty programs will withdraw redeemed miles from your account when you book a future award flight. And those miles won’t expire unless you cancel the award (and the miles are redeposited into your account with the original expiration date). So, if you’re sure that you’ll take the Sept 2025 trip, you should be fine. If you’re afraid you might cancel that trip, it may be worth paying to extend your miles.
Hopefully someone else with experience can chime in.
I have miles expiring Aug 31st. As long as I book a trip by that date I’m good, or does the travel have to be by Aug 31?
From what we understand, you only need to redeem miles by August 31 — not travel by that date.
I personally feel It’s better to keep in Krisflyer vs transferring it to Kris+ which has a very short expiry of just 6 months.
I lost 23k miles as didn’t realise credit expires in 6 months ( & no extension for COVID!) Repeated request to reinstate the miles with Kris+ customer service ended up in vain.
Customer service team of Kris+ is very strict with rules. My credit expired on Feb’22 & I requested them to reinstate end Mar, but after multiple reminders to get their feedback, finally got turned down on in May’22. So only transfer if you are going to use it immediately, or you will end up losing it like me.
Has anyone visited the New Silver Krisflyer lounge in SIngapore? Opened 23 November, and was reputed to have a “rest” area with recliners? I’ve a 7 hour transit 31 Dec and tossing up whether to book a transit hotel.
I was just wondering if transfer points from credit cards will extend the life of Krisflyer miles
Thank you
That “brick wall” mileage expiration just means that one should be highly transactional with Singapore KF by transferring points for a specific redemption, and nothing more. The program caters to people who frequently earn and burn, and that’s fine as long as you understand the rules of the game.
I have 75000 expiring krisflyer miles last yr so I booked for a trip to Asia but then had to cancel d/t HK demonstrations plus the Covid lockdowns. Doesn’t seem like Asia travel will be possible before it expires again based on the charts. What are my options other than paying to extend for another 6 months? Think I can use it for domestic flights with United.
Unfortunately, Krisflyer is more stingy than most airlines in terms of options to extned miles. Beyond the pay option highlighted here, you’re really only left with trying to get some value out of them, by either tranfering them out to another program or redeeming them one of several ways. But, with 75000 miles you should be able to find some options. For example, at one point you could transfer them to Virgin Australia’s Velocity program.
3 years is still better than many programs that’s only 2 years and I think Hawaiian Air is only 1.5 years.
A very good reason not to earn miles in this programme.
For this reason I only transfer credit card points into KF when I know there is an award I want and see availability. Otherwise I just accumulate on it when flying SilkAir as they aren’t a *A partner.
Unfortunate that they expire but it’s good there are transfer partners.
Didn’t know about the extension. Thanks!
Would be awesome to see a credit card option added for US consumers, a-la Lufthansa, that would keep points alive past the 36 month window.
its a pity they have a hard cap of 3 years on the miles for non-elite members
A total deal breaker for me. I simply don’t accept programs with hard (non-extendable) mileage expiry. You end up getting pushed into booking things you don’t need/want, just to use up the miles.
Hate being forced to use miles before an expiration date so never signed up for a program that forces usage. The extra discount you get on some routes is not worth the risk of miles expiring IMHO.
A big downside to the program.
Thanks for the heads up!
Wow, that’s quite hefty price for extention! Better come up with something else, if miles are expiring.
Thank you the information and the backdoor flexible travel rewards method.
What is a PPS member?
A level of elite status within the program
I currently have frequent flyer accounts with AA, DL, and UA. I am wondering if I should expand to foreign carriers too? I usually only fly internationally once a year.
Ed, an important thing to keep in mind is that foreign carriers may charge less than the domestic carrier for the same seat on the domestic carrier.
For example, it’ll cost you less to use Singapore miles to fly to Hawaii on United versus using United miles to fly to Hawaii. I’d recommend you ensure you’re collecting flexible travel rewards (SPG, Amex MR, Chase UR, Citi TYP) and then of course have all of the foreign carriers loyalty accounts as well.
They definitely do and no extension on the miles unless you pay.
It’s almost always safe to assume miles expire. I will say, for those that don’t, such as Delta, it’s a nice touch. We can all find plenty to say about Delta, but at least that is a perk.
Thank you for the reminder.
