This has probably been flogged to death but I'm still a little confused.

1)Please confirm that it is possible to now book Upper Class Seats on VS.
2)If there are VS seats available that are not CO codeshare inventory seats, is it sometimes possible to book by phone, or is what's online what you get.
3)I was hoping to use miles to book an upperclass reward for my wife and pay for a seat for myself. There's also a possibility that it would be CO BF one way and VS upperclass the other. When I try to price these seats, I get the follow message regarding the VS seats:

! Flight CO8229 does not offer BusinessFirst or First Class between seats between London, England (LHR - Heathrow) to New York, NY (JFK).
Flight CO8229 in the London, England (LHR - Heathrow) to New York, NY (JFK) market is in economy class.
Continental flight 8229 operated by Virgin Atlantic Airways.

Either an all CO BF or an all VS upperclass RT for my date can be had for approx. $2500 but for mixed CO and VS flights (even code shares) the price soars or I get the message above. Is there a way to book a CO/BF + VS/UC RT without thousands in additional cost?
