I've just flown on SQ602 and SQ607 in biz class and it was the crapy old biz class outfit ie. not flat bed. Does SQ have the new biz class on any of its flights between SIN and ICN?

If not, is there an airline that flies that route and has a better biz class.

I'm going to have to do a few red eyes on that route in the coming weeks and need all the comfort I can get.
