Singapore Airlines' KrisFlyer program, part of the Star Alliance, is highly regarded, especially for its premium cabin award redemptions. However, its miles are subject to a strict 'hard expiry' policy.

Singapore Airlines KrisFlyer Miles Expiration Policy

KrisFlyer miles have a fixed expiration date. Miles earned are valid for 36 months (three years) from the date they are credited to your account. They expire at the end of the equivalent month, three years later.

For example:

  • Miles credited on May 15, 2025, will expire on May 31, 2028.
  • Miles credited on December 1, 2025, will expire on December 31, 2028.

Crucially, account activity does NOT extend the validity of KrisFlyer miles. Earning more miles (e.g., by flying, transferring from partners like Amex, Chase, Citi, Capital One, or Bilt) or redeeming miles does not reset the 3-year clock on miles you've already earned. Each batch of miles has its own distinct 36-month lifespan.

Note: While standard miles expire, miles held by top-tier PPS Club members may have different validity rules as part of their elite benefits.

This 'hard expiry' policy requires members to be diligent about tracking when their miles were earned and planning redemptions before the deadline.

Keeping Track and Using Miles

Since activity doesn't prevent expiration for standard KrisFlyer miles, the only way to avoid losing them is to redeem them before their specific 3-year expiration date.

  • Check your KrisFlyer account statement regularly. It details how many miles are expiring and in which month.
  • Plan your redemptions, such as booking award flights on Singapore Airlines or Star Alliance partners, well in advance of the miles' expiration. KrisFlyer also allows redemptions for upgrades and sometimes non-flight options.
  • Singapore Airlines occasionally offers the option to pay a fee to extend the validity of expiring miles for a short period (often 6-12 months), but this is usually not the best value compared to redeeming them.
