although I think that the "Hampton Roads" area of VA is probably not served very well by HP, my personal vote would be for them...
By nature of your Gold status on HP, you will get a 100% mileage bonus (effectively double miles). Mileage from NRT to the US is sizeable. You can use those miles for travel on HP, CO and NW.
Even putting the miles into NW will not "top-off" a level equivalent to a reward ticket. If you have other travel plans w/in the coming months, that might be a strategy you might want to consider.
FYI HP = America West (AWA)
