A direct flight from Europe to China takes around 10 hours depending on whether you're flying to Beijing or Shanghai; flights with a stopover can take 18 hours or more.
Direct flights to Beijing or Shanghai are offered by several major carriers as well as China's own airlines. Alternatively, you can fly with a stopover via hubs such as Paris, Helsinki or London.
Compare airlines through your travel agent, since the first option shown isn't always the cheapest or fastest. Also check your baggage allowance carefully when booking.
