Are my KrisFlyer miles capped or do they expire?
Unlike some other cards, there is no miles capping. Your KrisFlyer miles are valid for 3 years, and you will be notified in your account statement before they are due to expire. As a KrisFlyer member, you may extend your miles once for 6 months at a nominal fee. If you are a KrisFlyer Elite Silver, KrisFlyer Elite Gold or PPS Club member, you may extend your miles for one year. Simply login to krisflyer.com to extend your KrisFlyer miles online. Please note: KrisFlyer miles that have already expired cannot be extended. For more information, please refer to the terms and conditions of the KrisFlyer programme available on krisflyer.
