There have been other cheap fares ex Prague to China on various carriers, but didn't see this route destination before, so thought i'd post it.
Bookable via KLM's website and books into Z/J which should earn decent miles onto most Skyteam programs.
Wide open availability it seems.
Oddly, it is not advertised in their promo campaign.
