KrisFlyer is a member rewards program for frequent flyers of Singapore Airlines, SilkAir and any select airline partners associated with the Star Alliance network. There are over 170 partners of the network worldwide. Members of KrisFlyer can gain special benefits, such as exclusive deals and earn miles whenever they fly, stay, charge, book, call, drive or shop with any of the partners in the selected network. KrisFlyer miles can be redeemed for free flights in more than 170 countries at over 1,000 different destinations across the world. KrisFlyer miles can also be used for upgrades at Singapore Airlines, SilkAir and participating partners. The basic concept is that the more you fly, the more KrisFlyer miles you earn. KrisFlyer members also receive upgrades to higher membership tiers (such as KrisFlyer Elite Silver and KrisFlyer Elite Gold) which offers members exclusive deals and greater recognition with participating partners.
