Mix KrisFlyer miles and cash | Singapore Airlines
Is mixing KrisFlyer miles and cash the same as redeeming miles for award tickets and flight upgrades?
No. When you choose to mix KrisFlyer miles and cash, you’re using your miles as you would a credit/debit card, Masterpass™ or PayPal. This means you have a choice of any available seat on any available flight operated by Singapore Airlines, when you book on
singaporeair.com.
