With the premier 2 cards, you will get;
1. Visa Infinite (VI)
2. Amex
The VI if you spend locally you will be rewarded with 2x points, the points is referred as Treat Points (TP)
Oversea spending with VI you will gain 5x TP
For Amex, both local and oversea spending of RM 1 will earn you 5x TP.
So to convert to Enrich Miles (EM), with Premier card you will need 4300 TP to get 1000 EM.
Example a return business class ticket to London cost you 93500 Enrich Miles; essentially means you need to spend approx. RM 80,410 to redeem a grab a return business class ticket. (Assuming all your spending are earning 5x TP)
With Enrich Miles redemption you are required to pay tax; fee depends on which airport you fly to. Example in europe, London is the most expensive follow by Paris and Amsterdam. London is RM26xx and Paris RM18xx if i am not mistaken.
As normal business class ticket cost in the region of 15k, your spending of RM80410 on Premier 2 card essentially save you approx. RM12000 on your air ticket. So this work out to approx 15% rebate.
If you read the link i've posted earlier, during end of year MAS will have promo that offers 55,000 EM only to fly a return business class. Which means you only have to spend RM 47,300 on your premier 2 cards. (Assuming all your spending are earning 5x TP) This reflect a rebate of approx 25%
Some concern here will be the stability of MAS and of course these are more like a luxury reward for you so if you prefer cold hard cash, just move on to card that offer cash rebate.
yeah~ seems this premier 2 card is the best. but too bad the requirement is 180k/annum.... so maybe i only can opt to apply for VI first..
