A330
Off Stand.
Hi, what a charming question!
Although I'm not adequately "in the know" regarding the Airbus A330, I can tell you what I think maybe correct.
I believe the IFE screens are in the seat backs. As regards to seating - well it depends on whether you wish to look over the wing or at the rear of the turbine!
I also believe TCX have the "Premier Class" (or called some other name) on their fleet, this is the front section of the aircraft and for an extra payment on booking you get the luxuary of larger pithced seats and maybe a more personal touch from the cabin crew, also sitting forward of the engines means you can listen to the "buzz" of the fan blades! (how sad!)
However, I'm sure there is somebody on PPRUNE who is "current" on an A330 who can give you a much more accurate picture/description of the aircraft and the best place to sit.
Enjoy your flight.
Brian.
