Hi all.
I have a flight from SEA to LHR this week. I can find some information but not a lot and confused by the layout/setup of the A330 300 and A300 900 for the transatlantic flights.

The 900 seemingly had a nice cabin along with a private screen/door you can close where as the 300 does not. I am unsure if I am getting old pictures or what have you but anyone know what to expect? Is there a private door of sorts on this flight config and cabin?
