Are these the same seats as the ones they installed on the 787 Dreamliner? As many of you must know, there have been a lot of complaints about those seats. If anyone has actual experience, I would love to know if these seats are attached to one another like those on the Dreamliner and, if so, is there one which is not attached? Apparently the movement when your seatmate moves is significant and, to many, quite disturbing.
