So the 77H is a partially re-designed J seat....or we will call it the LX seat...
So when it comes to the 787, sounds like some features will be similar but not others...hopefully nothing other than the colour scheme for J...
"These new features are a preview of what’s ahead with the 787. While we’re excited about the new products we’re bringing to you onboard these new 777s, there is a lot more to come with our 787s,
including a fully redesigned Executive First seat, "
I guess this is a good thing about it being fully redesigned (although when they use the term redesign to mean something other than what we currently have but basically something that someone else has)...unless instead of LX for J they use the J on the new LH747-8i and not something like on CX.
