The 747-200 seat map on VirginFlyer is for the Air Atlanta flights.
There is some confusion over the Upper Class layout though. It's thought the layout may have been changed, although when I asked that question to Virgin directly they said it hadn't. Hmmm...
Mind you, if you're not booked into Upper, that won't stop you looking at the other sections, which should still be correct!
And don't forget to add your seat ratings when you get back
