The Global Traveller offers a pretty extensive review of airline mileage expiration policies.
Like Kiwi Flyer, I was perplexed reading the February Inside Flyer cover story on mileage expiration to read that Singapore miles expire after 36 months of account activity.
: KrisFlyer accounts which have activity are valid for 36 months from the end of the month in which the last activity occurred, after which the membership accounts will expire.
I had always thought Singapore miles expire 36 months after they’re earned, and that the clock doesn’t get reset through additional account activity.
Sadly, Singapore miles do expire 36 months after they’re earned. I’m sitting on about 150,000 that I need to use sometime in the next 18 months…
