Yes, you can use Singapore Airlines KrisFlyer miles to book flights on Turkish Airlines, as both carriers are members of the Star Alliance. To do this, you search for "Star Alliance" awards on the Singapore Airlines website or mobile app. In 2026, award rates for these partner flights generally follow the "Star Alliance Award Chart," which often requires more miles than "Saver" awards on Singapore's own planes. Turkish Airlines is a popular choice for KrisFlyer redemptions due to its vast global network and highly-regarded Business Class service. However, be aware that you may need to pay carrier-imposed surcharges (fuel surcharges), which can be several hundred dollars depending on the route. If the flight does not appear online, you may need to call the KrisFlyer membership services to check for "partner award space" that isn't syncing with the website's search engine.
