will give it a try and report back.
OP reporting back: 75% success
went through the first 2 pax, got Biz class on PVG-BKK-HKT and HKT-BKK-PEK.
moved on to second reservation (also 2 pax), and got Biz on 3 of the 4 legs - everything except the PVG-BKK. Could have been better, could have been much worse.
