Well I go Virgin a lot to LA so its probably the same, they are always a 747 or an airbus depending on which time of day you go. You don't get to go upstairs, you either are in economy with all the rabble (which ain't too bad) or premium economy which is just further down towards the front end with slightly bigger seats and slightly better food and just a curtain to separate you from the economy, or you are in first class which is fabulous and you have the best of everything including massages, beauty treatments, full size bed, proper menu eat when you like etc. etc. . If you go to their website I think there is a section which shows you all the sorts of planes. You can choose your seat if you book online, or move it about at least.
