There are some good offers ex-HEL during the travel trade show. Some have Sat-Sun rules, but Seoul in C goes for 2150€ Sun-Fri. Not world shaking, but for direct flight a nice price. Pro ticket would be 2200€+ ...
Chinese destinations 1200-1700€
PS - the cheapest to ICN I found was ex-BUD for 1550€ (!!) in C but it would mean taking the Sat flight from BUD (OK, why not) and the Mon flight to ICN (so arrival Tue, no good for me)
