What Card Should You Choose?

How to Redeem Krisflyer Miles

Award Flights

When redeeming krisflyer miles redemption with Singapore Airlines, members can choose between Saver Awards, which require fewer miles but come with limited availability, and Advantage Awards, which need more miles but offer greater availability plus up to two stopovers per round trip.

To plan ahead, use the KrisFlyer Miles Calculator on SingaporeAir website to check how many miles you’ll need for your chosen route. It’s best to book early and stay flexible, as Saver Awards tend to sell out quickly.

Scoot Awards & Mix Miles + Cash

KrisFlyer members can redeem miles for Scoot economy tickets starting from just 4,500-7,000 miles for short-haul economy flights, making it an affordable way to use smaller balances.

Alternatively, you can choose to mix miles and cash when booking on FlyScoot website, with redemptions starting from 1,000 miles that can be applied not only to the fare but also to taxes and selected add-ons, giving you greater flexibility when flying with Scoot.

Nominate Others

You can nominate up to five people to redeem miles on your behalf, though you can only change nominees every one per year.

Tips on How to Use Krisflyer Miles

Stack credit card and promo bonuses

You can also boost your KrisFlyer balance by transferring bank reward points or credit card miles from major issuers such as American Express (Amex), Citibank and POSB.

These transfers are especially valuable during bonus transfer campaigns, when banks or Singapore Airlines offer extra miles, sometimes up to 15–20% more, on top of your regular transfer.

This makes it one of the fastest ways to accumulate KrisFlyer miles for future redemptions, especially if you use your credit cards frequently for dining, shopping, and travel expenses.

Use Kris+ apps

You can also earn KrisFlyer miles every day through the Kris+ apps, which make it easy to accumulate miles from dining, wellness, shopping, and travel experiences.

With Kris+, you can earn up to 9 miles per S$1 spent at partner restaurants, cafés, spas, and retail outlets in Singapore and selected countries. Together, these apps turn your everyday lifestyle spending into a steady stream of KrisFlyer miles.

Book award flights early

It’s always smart to book your KrisFlyer award flights as early as possible, especially if you’re aiming for Saver fares, which require fewer miles but have limited seat availability.

These seats often get snapped up quickly, particularly on popular routes and during peak travel seasons, so planning ahead gives you the best chance of securing them.

Be flexible on travel dates

To maximize your KrisFlyer miles, it helps to stay flexible with your travel dates and keep an eye out for limited-time promotions, such as bonus miles or discounted award redemptions on selected routes.

These offers can give you significant value, but availability is often restricted, so being adaptable with when and where you fly increases your chances of taking advantage of these deals.

Do KrisFlyer Miles Expire?

Yes, KrisFlyer miles expire after 3 years from the month they were credited to your account, regardless of activity.

For example, if you earned miles in January 2025, they will expire at the end of January 2028 if not redeemed. Unlike some frequent flyer programs that extend validity with new activity, KrisFlyer follows a fixed-expiry system.

However, Singapore Airlines offers options to extend expiring miles by 6 months (for KrisFlyer members) or 12 months (for Elite Silver and Gold members) for a service fee of 1,200 miles or US$12 (~S$15.4) per 10,000 miles (Please refer to the official website for the latest information). Another way to avoid losing value is to use miles for non-flight rewards such as seat upgrades, Scoot flights, Pelago activities, or Kris+ redemptions—before they expire.

Final Thoughts

KrisFlyer milestone rewards are versatile and increasingly accessible, whether you're flying, spending, shopping, or booking experiences. By leveraging credit card transfers, everyday spending partners, and strategic redemptions, you can earn and use miles efficiently.
