I fly OSL-PVG wiht LH a few times each year, and find C on LH OK. I have ordered three trips to US this year with SK (due to mileages earnings). Nice to be warned, but I guess biz is mostly about a seat in which I can sleep in, free and an OK choice of beverages, and OK food, whereas first is more like an experience. If I want excellent food, I'll go to a good restaurant.
