Hi Tony

if you log onto the virgin atlantic website (sorry posting the link is not allowed)
then using the left hand menu choose our story and then our fleet this will give you all seating configurations

if you have your booking ref or e ticket number you can use these to manage you flights again the link is on the home page and from there you can choose your seats and meal choices

a map comes up like the one magical dreams has posted and the red seats are the available ones grey are unavailable and purple are the ones you have choosen

i also have two seat ratings websites which i can dm to you if you let me know
