I suspect in a few years when the A380 becomes as common as muck, the economics will force open A380 premium cabins for KF Saver and *A redemptions.
I class is available on 77W and A380 flights but those are few and far between.
Currently the only way to redeem into Suites is by making a redemption in F before equipment upgauge to A380. With all SIN-LHR flights upgauging to A380, the only way to get to Europe in F on SQ is SQ25/26 SIN-FRA.
