Yes.

Always the case for all supplementary holders. All points / rewards go to principal.

The difference is that you set for the bill to be sent to supplementary to pay on their own.

Haha... I think there’s a little confusion here.

There’s two separate discussion we are having.

First thing first. The statement has the option to be sent to principal which either to include or exclude supplementary. To exclude here means the supplementary will receive their own statements and pay their own card. Here: principal receive one statement. Supplementary A get their own. Supplementary B get their own....
This is what is being discussed here. Principal can see all statements and all spending when principal includes them. All billed under principal cardholder statement.
In simple: one statement contains principal + supplementary A B and C.

Second which is the one you are referring is different. Although the statement goes to principal altogether, each cc payment needs to be transferred to individual for payment.
One statement: principal + supplementary A B and C, payment needs to paid to each card account separately.

😂

Let me know if it makes any sense lol

Yes, under a separate account.

Yes, you can see all principal and supp cards....all listed individually....

This in in contrast to Maybank, where can only see principal cards ....after viewing details of a principal card, then you can see a link to view the supps under that principal card....

The effect is then seen in real life....all cards in ambank, including supps, are considered equal, and are eligible for lounge entry.... Maybank supps have no eligibility.....
