I’m going to make a ~$20,000 purchase, I have an AMEX card and Citi premier miles, which one should I use or should I get a new card? ?

Wow $20k is a pretty large expense... I made a$8k expense recently, and we signed up for the AMEX KrisFlyer card to hit the bonus miles.

It was a pretty good deal! If you are going down the miles game.

Which AMEX card you using?

AMEX has targetted card holders for their recent promotions.

And also, i can't remember the details but spend $5k on the blue card in a single transaction and receive 5K extra miles. Receive 12K miles with a minimum spend of S$10,000 in a single transaction
