Navigating the world of airline loyalty programs can be a daunting task, but understanding the intricacies of the Singapore Airlines KrisFlyer program can unlock a wealth of travel benefits.

One of the most common questions surrounding KrisFlyer is whether the miles you earn ever expire.

The short answer is, yes, KrisFlyer miles do have an expiration date.

Specifically, your KrisFlyer miles will expire if there is no account activity (either earning or redeeming miles) for a period of 36 months.

This means that if you don't earn or use your miles within a 3-year period, they will be forfeited. - https://singaporefocusguide.com/blog/do-singapore-airlines-miles-expire/?unique_id_70hmjiy3
