Thank you Mark,
Never flown either route Shanghai or Beijing, hope to visit Terracotta Warriors, while there, from that point does it make any difference which airport, would like to try new first travelled LHR to Miami that was not NF, a really old plan .
Looking to tavel MAy next year, will the duststorms be over , is it a good time to visit the sites before the real busy period.
Sorry for all the questions, any advice much appreiacted.
