I'm flying to Europe (from SIN) in two weeks. At the moment, both segments show no availability for upgrades (well, the LHR-SIN segment shows availability of Full awards, but that's as good as nothing). I just wanted to find out how often last minute availability for upgrade redemptions shows up? I have enough miles with my credit card company, but it would take about a week to transfer them into my KrisFlyer account. At the same time, I'd rather not transfer them in if there's no chance of using them, as they don't expire where they are at the moment. Thoughts?
