For anyone who's interested - was checking to see if was going to be cheaper to do USA-HKG-USA or vice versa during the summer.

All these from Nan Hwa Travel in HKG (anyone wants contact details, drop me a line)

HKG-East Coast USA:

6960 HKD 30 Days V class - until end June (Mon-Thur depart)
8460 HKD 45 days V class - until end June (Mon-Thur depart)

High Season: 13 July - 9 sept: 10,370 HKD (30 day V class)

The 30 days fares seem good if you want an upgradeable fare...
