KrisFlyer miles chasers, the KrisFlyer UOB Credit Card might be the easiest, most fuss-free miles card for you. This card lets you earn KrisFlyer miles directly with no conversion fee (unlike miles cards like the UOB PRVI Card we also reviewed).

The bonus earn rates are also generous, at up to 3 KrisFlyer miles per dollar (mpd) spent on Singapore Airlines, Scoot, KrisShop and Kris+ purchases. You can get the same rate on dining, food delivery, online shopping and travel, and transport expenses—that is, if you spend at least $800 annually on Singapore Airlines, Scoot and KrisShop.
