CX offers some great biz fare from China to Southeast Asia, I have found that the PEK - BKK route always gives Biz saver fare which is only about 900 USD return including tax and all surcharges.
Each return trip from PEK to BKK gives you 280 status credit. I just reckon that for someone based in mainland, this would be a good deal.
As to the 4 sectors on QF or Jetstar hurdle requirement, I think it could be done by flying Jetstar's southeast flights where there are some good deals around!
Anyone here has other recommendations for quickly accumulating QF status credit?
