I have some Krisflyer points that are expiry in January, February, and March.
In order to have enough points to redeem, I need to credit some Lufthansa flights in December to Krisflyer.

My question is about the redeeming my points for flights in the future.
Does it matter when the flights are versus the expiry?
If I use the points before expiry, can I just book for flights after they would have expired, say for June or July? It doesn't matter that the points would expire in January, February or March???
Seems like a silly question but I don't want to be caught out. Also, has there been a change to the points chart? The one on google says 50k for business redemption and halve for one ways, but all searches show 33.5k required.
