One thing to note is if you are flying during the day across the Atlantic, you may not necessarily want to be in a window seat. I did that once to SJC and because the windows only tint but do not go completely black, the sun may still cause annoying reflections in the IFE screen. I also found that the window got really hot to touch. So for my next SJC flight I picked 7E over 7A and was much happier.

This is obviously down to personal taste. Being in 7A on the first trip gave me excellent views as the plane flew in over San Francisco and down towards San Jose. Swings and roundabouts. :-)
