Updated: KrisFlyer miles expiring? 12 ways to save them from the scrapheap

Expiring KrisFlyer miles needn't be resigned to junk status. Here are a dozen ways to get some value out of them.

Many of you will know that last week Singapore Airlines finally awarded some breathing space to KrisFlyer members whose miles are expiring over the coming months, in light of the almost complete inability to make future travel plans due to the COVID-19 outbreak.


It’s not just at times like these you need to keep an eye on your miles validity though. We get regular emails throughout the year from KrisFlyer members whose miles are expiring, asking us what they can do to prevent it, or alternatively get at least some value from the miles before they vanish.

In a nutshell there are four principal options:

  • Use them to redeem a flight before they expire (your trip can be up to a year away).
  • Pay a fee to extend them for 6 or 12 months (you can only do this once).
  • Sacrifice around half of them, but keep the rest for another 3 years.
  • Cash them out somehow.

Which option is best for you will depend on your upcoming travel plans, the number of miles you have expiring and the number of miles you have in total.

How KrisFlyer miles expiry works

First a quick rundown on how your KrisFlyer miles may end up expiring. In common with many airlines (but to be fair not in common with many others!), Singapore Airlines applies a fixed validity period on your KrisFlyer miles.

No matter how you earn your KrisFlyer miles (from revenue flights to credit card spend, from Chope vouchers to foodpanda) they will expire on the last day of the month 36 months following the month in which they were first credited to your account.

KrisFlyer Miles Expiry A member’s KrisFlyer miles will expire after three years at the end of the equivalent month in which they were earned. For example, miles credited to a member’s KrisFlyer account in July 2019 will expire on 31st July 2022.

The ‘oldest’ miles in your account are used up first when you make any kind of redemption. For most of us that means there’s no need to worry about miles expiry. We churn through what we earn more frequently than once every 3 years.

Your KrisFlyer account page on the SIA website or mobile app will show you how many miles you have expiring in the next six months (listed by month). Your KrisFlyer account statement, which should arrive by email each month, also shows these details:

Expiring Miles
In this example you have 348 KrisFlyer miles expiring on 31st July 2020 and a further 20,000 expiring on 31st August 2020

Remember, at the time of writing KrisFlyer miles expiring between April 2020 and August 2020 will be extended by six months.

If you thought you could circumvent the miles expiry issue by making a flight redemption several months into the future with miles that are just about to expire, then later cancel the ticket and redeposit the miles, that won’t work unfortunately.


Every KrisFlyer mile in your account has a ‘memory’ – it knows exactly when it was earned, including miles redeemed for a flight you haven’t taken yet.

If any of the miles you used for a flight redemption would have expired at the time of cancellation / redeposit request you won’t get those miles back.

PPS Club

There’s one bit of good news – if you’re a PPS Club or Solitaire PPS Club member, your KrisFlyer miles never expire. Any KrisFlyer miles in your account stop having a ‘memory’ expiration countdown once you become a PPS Club member.

PPS Club

If you fail to requalify for PPS Club in future, all the KrisFlyer miles in your account are reset with a full three-year validity period from the month you drop back into a KrisFlyer tier.

For example if you drop from PPS Club to being a KrisFlyer member on 1st June 2020, all the KrisFlyer miles in your account at that time will now expire at 23:59 hours Singapore time on 30th June 2023.

The options

Here are the 12 options, ordered best to worst by value, for your expiring KrisFlyer miles.

1 A flight redemption

Value: 1.90+ cents per mile
Min. expiring miles: 7,500
  • Best value for your miles.
  • Ability to book a year in advance.
  • You must have some travel plans.
  • Sufficient award availability must match your travel dates.
  • If you cancel the ticket after date the miles would have expired, you’ll lose them.

This one might seem a bit silly or obvious to include, after all if you could have used your expiring miles to book a redemption ticket surely you would have done by now?

What many people don’t necessarily appreciate however is how far in advance you can lock in an award ticket using KrisFlyer miles, and the breadth of Star Alliance and partner airline award options out there, which might help.

Fresh availability of KrisFlyer award seats in 355 days time on Singapore Airlines and SilkAir, for example, is loaded at 8am SGT each morning (GMT+8), and this is often a good time to jump on a pair of Business Saver redemptions a year out.

We’ve also spoken to people who think you must redeem and have travelled on an award flight before your miles expire – that’s not the case. You must have booked the award ticket, but it can be locked in close to a year in advance. The fact you’ll be sitting on a flight using miles which would have expired up to a year before doesn’t matter.

With this option you’re looking at trying to lock in a redemption ticket or upgrade (where permitted):

  • On a Singapore Airlines or SilkAir flight.
  • On a Star Alliance member airline flight (most are now searchable and bookable online through KrisFlyer).
  • On a partner airline flight, like Alaska Airlines or Virgin Australia.

Since these options by far represent the best value you can extract from KrisFlyer miles you should absolutely exhaust them first in our opinion, before moving on to any of the following steps.

2 Extend your miles for a fee

Value: 1.73 cents per mile*
Min. expiring miles: No minimum
  • Some breathing room.
  • An opportunity to still get top value for your miles for a small fee.
  • If you don’t go on to use the miles for a flight redemption, it’s wasted money.

* Assuming you pay cash to extend your miles, then go on to redeem the extended miles and achieve 1.9 cents per mile in value.

One option for your expiring miles is to extend their validity by 6 months. You can choose to pay US$12 (around S$17) per block of 10,000 expiring miles, or sacrifice 1,200 miles per 10,000-mile block to achieve the same extension.

KrisFlyer Elite Silver and Gold members get 12 months additional miles validity for the same fee or miles cost (and remember miles never expire for PPS Club members).

First point to note here if you are considering this option is that it’s probably better to use cash to extend your miles than sacrifice a portion of the miles themselves. If you’re extending the miles ideally you want them all to still be there for one thing, and as you should never be redeeming then at less than 1.9 Singapore cents of value per mile, 1,200 miles (implied value S$23) is a bigger price to pay than the cash equivalent (S$17).

Before you go ahead with this though, remember that paying to extend your KrisFlyer miles is only useful if you are fairly certain it will help you use them.

It’s also a one-time offer, you can only extend expiring miles once.

3 Transfer to Shangri-La points for ‘Instant Dining Awards’
Value: 1.20 cents per mile
Min. expiring miles: 20,000
  • Shangri-La Golden Circle Awards points are valid for 3 years.
  • Redeem at 23 bars and restaurants in Singapore and over 500 worldwide.
  • High minimum transfer quantity.
  • You may have no use for a Shangri-La GC ‘Instant Dining Award’.
  • You may argue that many of these bars and restaurants, which tend to be in hotels, are overpriced anyway, eroding the ‘value’ if you’d never otherwise consider drinking or dining there.

Transfers from KrisFlyer to Shangri-La Golden Circle (SLGC) Awards points are subject to a minimum transfer quantity of 20,000 miles, the highest of all the options for your expiring miles.


If you do have enough expiring miles to warrant this option your KrisFlyer miles will transfer to SLGC points at a 12:1 ratio. The key to this rewards scheme is their ‘Instant Dining Awards’ program, where you’ll likely achieve best value per point. Each SLGC point is worth 10 US cents against a bar / restaurant charge at a participating outlet.

There are 23 such bars and restaurants in Singapore alone and more than 500 worldwide.
