normally u wait 2 weeks after the transaction done only BT right since it will take 14 days ?

but you need to make sure your watami cc has a credit limit of at least 20% higher than the amount you swipe in your ocbc. and if you are going to swipe your watami cc for other things besides doing bt, then you need to have much higher than 20%.

may I ask why 20% ?

it's around 20% bcs you can only do bt using 80% of your credit limit.

hmm I check the amount I wanna charge is about the same as the watami cc limit so I need to increase temporary limit to do this ?

so u can continue to use your watami cc without any charges on it after BT from amex unlike citibank and hsbc ? equal installment means total amount divided by 6 months ? am gonna make a large amount to ocbc titanium then can consider BT to watami next

i'm afraid you have to do so...

What is the reason that can be given to temporary increase CL? Can we tell them is due to BT? Or need to give better reasons?? 

How to know when is my card approval date?

approval date=activated card date?

the best reason is for medical or traveling. of course cannot say is for bt. 

But will they void the transaction if found out usage is not per mentioned.lol

Examples, swipe my Amex and BT Amex statement balance to AEON Watami cc. Both are existing cards. 0% interest on 6 month equal installment amount without charges.

No one time fee for watami BT?
Is this another great feature of watami?

Like maybank they charge upfront  one time fee of 3%. Although they always got promotion 0% interest for 6 month, upfront fee is always there.

No charge when you pay full statement balance (swipes + BT monthly) before due date. Never try Citi & HSBC before.
E.g. BT 3k, installment 500 x 6 months.
Yes, done BT ocbc to watami, no problem.

once they lift up the credit limit, then you can swipe whatever you want... 

normally void do by merchant 

when you BT to watami u still get 1% cash back for titanium ?

Definitely, why not.. titanium is titanium, watami is watami..Each "milking" its own benefit.
