Singapore Airlines promo fares: not great, but stackable codes sweeten the deal.

Singapore Airlines' latest promo fares to 63 destinations are 'usually not particularly attractive,' as the source notes. But you can stack with credit card promo codes: DBS S$50 off (14-20 Jul), HSBC S$60 off (28 Jul-3 Aug), Citi Prestige S$60-S$120 off (21-27 Jul), or Mastercard S$50 KrisPay miles (14 Jul-9 Aug). Alternatively, the KrisFlyer Spontaneous Escapes promo offers 30% off miles redemptions, which may beat cash fares for premium cabins.

The play: Book roundtrip from Singapore by 9 Aug 2026 and apply the applicable promo code, or check KrisFlyer Spontaneous Escapes for a 30% miles discount instead.
