Singapore Airlines just emailed an announcement for their PPS Club members about the ability to book Suites on the A380 on saver award level using KrisFlyer miles. Note that these have not been made available for bookings using partner airline miles like United.
At the same time, Singapore Airlines have revised and changed some mileage requirements for these awards. You can access the PDF file here.
This is a welcomed change for KrisFlyer members that can now apart their miles in style. We’ll see if these will ever become available using miles from Star Alliance programs.
