Hainan Airlines offers daily non-stop connections between Brussels and Beijing with a comfortable Airbus A330. From Beijing you can take a connecting flight to a wide range of destinations in China, for a very small supplement. For example you can fly to Shanghai and return from Hong Kong, with a stopover on the away or return flight in Beijing, for a little supplement compared to a return ticket from Beijing. So, if you intend to travel to China from Belgium, the best way to do that is without any doubt with Hainan Airlines.
We recommend you to take the Flight Selection travel insurance of Allianz Global Assistance (from €52 worldwide).
