This might be more like novelty, but still pretty amazing fare between Europe and China. Tibet Airlines operates twice weekly (Mondays and Thursdays) at least until 14OCT between Helsinki and Jinan with A330-200, no idea about the seat or the service concept, but if you want to try something exotic, here you are. And the best part is that this fare seems to be bookable one-way with more or less half of the return fare.
