You see China Southern serving Beijing? Or a completely different carrier serving Beijing (that'll be Air China), or China Southern serving Guanghzou? Cos right now they're flying low yield tourists on a B787 outta LHR and not making a lot of margin.
So if they can't make LHR work, what makes you say there's "no doubt" this will lead to a scheduled service from BHX to PEK or possibly CAN or throwing one more into the mix, PVG?
