Which credit card is the best for airline mileage?

Hi, I'm the founder of whatCard.sg. You can try checking out the blog for weekly card reviews.

Regarding best miles card, it depends on your lifestyle really because the card companies do give bonus miles in certain categories. If you know which merchants you regularly transact act, you can again go to the site to use the merchant search tool to see which card gives you the most miles for spending there.

Hi! Adding on from Kenneth's post, I think it's also important to see if you want just one card, or if you are okay to spread your miles among different cards for different purchases. As a guide these are some of the more popular cards in the field:

• DBS WWMC 4mpd for online spend cap at 2k a month. Points expire in 1 year if I remember correctly
• DBS altitude/Citibank premier miles card: basic entry level miles card that gives 1.2mpd for most spending (might get more mpd on certain categories like online travel etc), points don't expire
• the new BOC miles card: current promo till Dec that earn more than the altitude/premier miles. However have also read reviews that the card takes really long to arrive, and their internet banking is quite primitive 😂 points have expiry date 1-2 years too.
• amex krisflyer is the only card that credits miles directly into your krisflyer account, instead of accumulating bank points then transferring in a lump sum of points.

Also, collecting air miles usually requires some effort too! Bear in mind if you just want one card, miles collecting might be slower, and make sure to check the points expiry with the bank. But if you spread yourself out too much with many cards, beware of orphan points when you don't hit the min points to exchange them to miles.

I hope I did not just confuse 😂😂 have fun with the miles game! I'm still learning too :)
