We are going to be flying Business Class from phx-lhr and then from lhr - dar. The first leg is on a 777 with cradle seat configuration and the second leg is a 767. I am looking for some input into seat selection per these scenarios below.

It looks like, on the seat map, that the 777 business class rows are 10 - 17. We were thinking trying to get rows 14 & 15 seats A & B (there are four of us, two couples traveling). We are concerned that if we are any closer forward it will put us to close to the restroom and any further back to close the separation between business and coach - where people sometimes tend to stand.

On the 767 the choice is even harder as the 767 the configuration we will be on does have first so the row choices are 6 & 7, right behind first but in from of the galley, or 10 - 13. We are thinking rows 11 & 12 but am wondering if anyone has ever been in 6 & 7 and would that be a better choice or is there a wall our curtain between first and these two rows of business class seats. Should we be in 6 & 7, are we ok where we are, or is there a better choice?

Any help on what is the optimal seat for either of these flights would be appreciated.

Many Thanks!
