When you use your Singapore Airlines KrisFlyer miles to book an economy-class ticket, you may receive a value of around 1.1 cents to 1.5 cents per mile. You usually get better value when booking business class tickets, where one mile could be worth more than 2 cents. If you redeem your miles for non-flight rewards, the value drops to less than 1 cent per mile.
You earn miles when you fly with Singapore Airlines or any of the program's airline partners. You can also earn miles when you shop at KrisShop.com and by spending with the program's partner merchants.
You can redeem your miles to fly with Singapore Airlines and the program's partners. Other ways to use your miles include shopping at KrisShop, donating them to charity and paying for car rentals and hotel stays. Using a combination of miles and cash to book flights is possible.
