Singapore Airlines bookings earn KrisFlyer miles via two parallel paths: your credit card's mpd, and SIA's flown-mileage programme. The right card converts spend directly to KrisFlyer at the highest possible rate without a transfer fee. KrisFlyer-branded SG co-brands dominate this category — they credit miles straight to KrisFlyer at elevated rates on SIA / Scoot / Krisshop spend.
AMEX
2 KrisFlyer miles per S$1 on Singapore Airlines flights (singaporeair.com/SIA app, SGD), Scoot (flyscoot.com/Scoot app, SGD), KrisShop (onboard or krisshop.com), Pelago (excl GPay/ApplePay).
AMEX
2 KrisFlyer miles per S$1 on SIA / Scoot / KrisShop / Pelago — same SIA Group bonus as KF Base.
AMEX
2 KrisFlyer miles per S$1 on SIA / Scoot / KrisShop / Pelago — excluded from S$3,800 threshold calculation.
These are the objective top picks. Perqa narrows them to the cards in your wallet and tracks your spend so you always use the right one.
Try Perqa — freeUOB KrisFlyer Card pays 3 mpd on SIA / Scoot / Krisshop (after qualifying spend, miles credit directly to KrisFlyer — no conversion fee). AMEX KrisFlyer Ascend pays up to 3.2 mpd on flights via KrisFlyer Spree. Both clear 3+ mpd; convert directly to KrisFlyer.
KrisFlyer co-brands win if SIA is your primary redemption (no conversion fee, direct mile credit). General miles cards (UOB PRVI Miles, DBS Altitude) win if you convert to multiple airlines or have a non-KrisFlyer strategy.
Yes — your card sees the merchant as the OTA (Agoda, Booking.com, Expedia) under MCC 4722. You earn travel-category mpd from your card. But the SIA-flown-miles layer requires booking via SIA direct or a KrisFlyer-partner channel to credit KrisFlyer.
