Hi, CIMB does not convert to KrisFlyer miles. It is best to convert to Enrich Airmiles.
1) Enrich offers instant flight redemptions/confirmations, whereas KrisFlyer sometimes has waiting lists.
2) Of course KrisFlyer experience is said to be much better.
3) However, don't discount Enrich Airmiles yet. You CAN redeem any flights within the One World Alliance which includes the very expensive Japan Airlines. Just need to call Enrich and be prepared to set aside 2 hours of your day to do this.
For your reference
1) Officially (based on CIMB rates), RM 1000 spend = 10k Points = 1000 Enrich airmiles or RM 25 cashback (effectively 2.5% cashback). Therefore, 1 Enrich mile = RM 0.025 (you can convert to cash with CIMB)
2) If you redeem MAS Business class, 1 Enrich mile is worth up to RM 0.041656 for Business class redemption and worth less for Economy class redemption.
(Will need to compare with the cheapest flight ticket in the corresponding cabin class)
3) *If you redeem Business class with Japan Airlines, you can maximise the value of your Enrich mile. 1 Enrich is up to 0.17319 (about 4 times the value with Enrich business class)
For example, I recently redeemed a one-way flight from Tokyo to London Heathrow.
The cheapest one-way business class is RM 23k with Japan Airlines EXCLUDING taxes
Always good to share

to help make the most of our money indeed
Hope to hear about tips from other forumers.
4) If you manage to gain a business class with Japan Airlines via CIMB WTE - Enrich, the annual fee of RM 1200 will be extremely worth it!
Whereas you can redeem the same business class using 131000 Enrich Airmiles via Malaysia Airlines call centre. Note that the miles required for One World Alliance are based on distances - and are fixed until new changes are announced.
the taxes are fixed at RM 1693 per person (for both Economy & Business class)
4) There is however drawback. It seems that there is only one business class seat for redemption via Malaysia Airlines One World Alliance for each business class flight. So, if you are travelling alone, it is great. Otherwise, may have to settle for Economy class for your partner or family's sake.
