I'm planning a trip to China in April or May, 2012. Like many others, I'd like to take advantage of BA's 100k to Asia in Biz with unlimited stopovers before it's gone. Does BA allow a routing like this? LAX-HKG-PVG-CTU on CX and/or KA? on Google map, it looks like HKG is west of PVG, but I could find direct flight on CX from LAX-PVG, does CX fly LAX-PVG? or would it be ok if HKG is just a connection? I'm based in Seattle, is my only option to book a separate flight on AS to LAX?
