I think timing for good Asian connections does not make sense if it compromises European connections. HEL is much too small of an O/D of its own. Finnair needs the feeders to/from Europe. They also need to keep the morning flights from HEL and the evening flights to HEL interesting to keep the whole business viable.
I am not saying this because I am a European living in Europe. As an HEL-based flyer myself, I would benefit more from convenient Asian connections.
