Credit Cards
There are no credit cards that earn KrisFlyer miles directly, so your only options are ones that earn transferable points. Luckily, there are a lot of them. Of the cards below, I prefer to use the American Express Membership Rewards cards to transfer miles to Singapore Airlines, but I have also transferred from Chase Ultimate Rewards and Citi ThankYou in the past. You can view the current best offers for all of these cards at Credit Cards.
| Credit Card | Minimum Signup Bonus / Spend / Time |
| American Express Premier Rewards Gold Card | 50,000 MR / $3,000 / 3 months |
| American Express Business Gold Rewards Card | 75,000 MR / $5,000 / 3 months |
| American Express Platinum Card | 100,000 MR / $5,000 / 3 months |
| American Express Business Platinum Card | 100,000 MR / $5,000 / 3 months |
| Chase Sapphire Preferred Card | 40,000 UR / $4,000 / 3 months |
| Chase Ink Plus Business Card | 50,000 UR / $5,000 / 3 months |
| Citi ThankYou Premier Card | 50,000 TYP / $3,000 / 3 months |
| Citi ThankYou Prestige Card | 50,000 TYP / $3,000 / 3 months |
| American Express Starwood Preferred Guest Credit Card | 25,000 SPG / $3,000 / 3 months |
| American Express Starwood Preferred Guest Business Credit Card | 25,000 SPG / $5,000 / 3 months |
American Express Membership Rewards, Chase Ultimate Rewards, Citi ThankYou Points, and Starwood Preferred Guest Starpoints can all be transferred to Singapore Airlines KrisFlyer at a 1:1 ratio; however, Starpoints also provide a 25% bonus if you transfer in 20,000 point increments (meaning every 20,000 points becomes 25,000 KrisFlyer miles).
Credit CArd Churning
The Citi cards can be churned. The two Chase cards (Sapphire and Ink) can be churned as well, but this may be difficult to do in practice. For more information, see How To Earn A Signup Bonus Multiple Times.

Miles Expiration
Unlike other airline mileage programs, KrisFlyer miles expire 36 months after they are earned, and activity in your account does NOT extend your expiration. The only way to extend your expiration is to pay a fee, which gives you six more months to use up your miles.
