After a couple of days of systems down, I was able to book SIN-IST-LHR on TK in I class when United as well as KVS showed no availabiity. May be the latest changes are working in our favour? Reminds me of the good old days when you could book SQ long haul in premier cabin using Lifemiles!!

Some interesting changes
a) Flights from Australia to Europe via BKK now working again, not just MUC
b) Engine even more erratic than before, quite possible to get different results from the same query at different times of day - maybe they lowered a time-out?
c) eg SQ C awards not showing at the moment but were visible yesterday
