[MENTION=613867]AceCobra1[/MENTION] I'll be in HKG roughly the same time as you - I'm using GF LHR-BKK and then EK BKK-HKG with a couple of nights in BKK at each end. Whole thing about £1500.
Better timings for me than the QR options that had very, very long layovers in DOH to get the lower fares.
Downsides - no mileage earning for me in any useful programme and the GF A330 to from BKK.
