Singapore KrisFlyer miles are some of the most valuable and flexible airline miles in the world. Even if you never use them to fly to Singapore, you can use them to book flights on a variety of airlines, including United Airlines. However, KrisFlyer miles expire if you don’t use them in time. Find out when they expire and if there’s a way to prevent expiration.

Do Singapore KrisFlyer Miles Expire?

KrisFlyer miles expire 36 months from the month you earn them. So, for example, any miles you earn in January 2020, expire on January 31, 2023.

Even if you regularly earn or redeem Krisflyer miles during the year, your miles expire after three years.

While three years is a relatively long time, you will want to avoid stockpiling points. Airlines with shorter expiration periods at least renew your entire balance when you have any account activity.

Renew KrisFlyer Miles

It’s possible to renew your KrisFlyer miles (for a fee!) for up to one year, depending on your loyalty status. Regular KrisFlyer members can only renew their miles up to six months. KrisFlyer Elite Silver, Elite Gold, and PPS members can extend miles up to one year.

Singapore Airlines gives you the option to extend miles in three-month increments. The exact fee you pay depends on your loyalty status. As a point of reference, it costs 1,200 miles and $12 for every 10,000 miles you redeem. Elite members can pay smaller fees.

You will need to renew your miles before they expire. Expired KrisFlyer miles cannot be extended.

KrisFlyer miles also cannot be transferred to another KrisFlyer account. You either use them or lose them.

Earning KrisFlyer Miles

Despite expiring after 36 months, KrisFlyer miles are relatively easy to earn and redeem. One way is to fly Singapore Airlines-operated flights and earn miles. If you love to travel, an easier option is having a credit card that earns KrisFlyer miles.

US residents don’t have direct access to a co-brand Singapore Airlines credit card. However, several cards let you transfer credit card points to your KrisFlyer account.

The Platinum Card from American Express

The Platinum Card® from American Express can be your best all-around option for Singapore Airlines. You earn 5x Membership Rewards on flights booked directly from the airline or on, up to $500,000 per year on these purchases. Then, you can transfer them at a 1:1 ratio to airlines, including Singapore.

Another reason to consider the Platinum Card from American Express is for its complimentary airport lounge access. If your ticket doesn’t let you access the KrisFlyer lounge, chances are the airport has a Plaza Premium, Priority Pass (enrollment required), or Centurion lounge. American Express gives you free access to these three lounge networks plus Airspace and (when flying Delta) Delta Sky Club.

Any American Express credit card that earns Membership Rewards on purchases lets you transfer points at a 1:1 ratio. This card’s annual fee is $550 (See Rates & Fees).

Chase Sapphire Reserve

Singapore Airlines is also a 1:1 transfer partner with Chase Ultimate Rewards. The Chase Sapphire Reserve® lets you earn the most miles of the three eligible cards. You get 3x points per $1 spent on all dining purchases. You’ll also earn 3x points for each $1 spent on travel after spending $300 annually on travel. Plus, earn 1x point per $1 for everything else.

Ultimate Rewards points are worth 1.5 cents each when booking award travel through Chase if you don’t want to transfer them.

Premier air travel benefits include:

  • $300 annual travel credit
  • Priority Pass airport lounge access
  • Global Entry or TSA PreCheck application fee credit

Capital One Venture Rewards Credit Card

The Capital One Venture Rewards Credit Card earns unlimited 2x miles per $1 spent on every purchase. While each purchase earns double miles, the transfer ratio isn’t as strong. You can transfer miles at a 2:1 ratio to Singapore Airlines. You get fewer KrisFlyer miles, but transferring can still get you a better redemption value than redeeming them for a travel statement credit.

Owning the Venture Card also gives you a fee credit of up to $100 for Global Entry or TSA PreCheck.

New Capital One Venture Rewards Credit Card cardholders can earn 100,000 bonus miles after spending $20,000 on purchases in the first 12 months from account opening, or earn 50,000 miles after spending $3,000 on purchases in the first 3 months.

Citi Prestige

The information for the Citi Prestige® Credit Card has been collected independently by Johnny Jet. The card details on this page have not been reviewed or provided by the card issuer.

Your Citi ThankYou points can transfer to Singapore Airlines (and other airlines) at a 1:1 ratio. The Citi Prestige is an exciting option for air and hotel rewards:

  • Earn 5x ThankYou points on flights and restaurants
  • Earn 3x points on cruise lines and hotels
  • All remaining purchases earn an unlimited 1 point per $1
  • Priority Pass airport lounge access
  • $250 annual travel credit
  • 4th hotel night free on 4+ night stays (up to twice per year – exclusive of taxes and fees)

Each point is only worth 1 cent each when booking any award travel on using your Citi Prestige.

Another notable Citi alternative is the Citi Premier® Card. This card, too, lets you transfer points at a 1:1 ratio.

Redeeming KrisFlyer Miles

The best KrisFlyer miles strategy is transferring credit card points to your airline account when you’re ready to book a flight. These transfers can take up to 3 days on average to Singapore Airlines as a heads up. It’s wise to make sure award space is available before you transfer.

These are some of the award flights you should consider booking first.

Singapore Suites is one of the best flying experiences around.

Singapore Suites

Select long-distance routes have the luxurious Singapore Suites class. You get a private room with a lie-flat bed, which makes this one of the best first class flight experiences. One of the cheapest routes can be from New York to Frankfurt for 86,000 KrisFlyer miles one-way.

Alaska Airlines to Hawaii

Award flights from the U.S. west coast to Hawaii cost 24,000 miles round-trip in economy on Alaska Airlines. Most legacy airlines require a similar amount for a one-way flight. If you’re looking for an excuse to visit this tropical paradise, consider this route if you can fly from California, Washington, or Oregon.

Star Alliance Partner Flights

Unless you own a Chase credit card, it can be difficult to book Star Alliance flights with another bank’s credit card. Singapore Airlines is a “backdoor option” to fly United Airlines and other Star Alliance partners. Main cabin round-trip award flights within North America start at 25,000 miles. This is competitive with booking directly through United or other airlines depending on availability.

Singapore Airlines KrisFlyer miles expire 36 months from the month you earn them. You can pay a fee to extend them up to 6 months with basic KrisFlyer loyalty status. A better strategy can be having one of the best travel credit cards that lets you transfer points to your KrisFlyer account on a 1:1 ratio when you’re KrisFlyer has the best flight options.


Do Singapore Airlines KrisFlyer miles expire?

Yes, all KrisFlyer miles expire 36 months from the issuing month. For example, any miles you earn in January of 2020, will expire at the end of January 2023. Regular KrisFlyer account activity, such as earning or redeeming miles, doesn’t renew your balance.

It’s possible to renew your miles for up six months as a basic KrisFlyer member or up to 1 year for elite or PPS members. However, you will pay a fee, and you must renew the miles before they expire.

Expired KrisFlyer miles cannot be reactivated. Nor can you transfer KrisFlyer miles to another member’s account.

How much does it cost to renew KrisFlyer miles?

The mileage renewal fee for most KrisFlyer members is 1,200 miles plus $12 for every 10,000 KrisFlyer miles you renew. This fee can be less for KrisFlyer Elite and KrisFlyer PPS members. You must request this renewal before your miles expire.

Which credit cards let you transfer points to Singapore Airlines?

Several credit card rewards programs are Singapore Airlines KrisFlyer transfer partners.

These three rewards programs let you transfer miles at a 1:1 ratio:

Capital One also lets you transfer miles but at a 2:1 ratio meaning 1,000 Capital One points are worth 500 KrisFlyer miles. Qualifying Capital One cards include the Capital One Venture Rewards Credit Card and the Capital One Spark Miles for Business or Spark® Miles Select from Capital One® business credit cards.

You might also be able to transfer points from a Marriott Bonvoy credit card, but the ratio is likely to be 3:1. Transferring 1,000 Bonvoy points can only be worth 333 KrisFlyer miles at this rate.
