Hainan
As to LHR with Hainan, I assume that with CA doubling capacity on LHR-PEK, Hainan are starting too? #really?
Unless something has changed Hainan wouldn't be able to launch PEK-LHR as there is already one Chinese airline flying the route; assuming Air China have pulled LGW it's more probable Hainan will go there. Either way, going from 0 to 2 UK points in the space of a month is quite a bold move.
