Do Singapore KrisFlyer Miles Expire?

KrisFlyer miles expire 36 months from the month you earn them. For example, miles earned in March 2023 will expire on March 31, 2026.

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.

Additionally, it’s not uncommon for travel programs to devalue their miles. This was the case for Singapore Airlines in July 2022, so KrisFlyer miles are not as valuable as they used to be.

Award flights from the U.S. west coast to Hawaii cost 8,500 miles one-way in economy on Alaska Airlines. Most legacy airlines require a substantially more 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.

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 27,000 miles. This is competitive with booking directly through United or other airlines depending on availability.
