They'll be seriously missed in this household. The upper deck in Club Class was like being in a private jet. My wife - who has flown BA enough to be Gold For Life - always asked for and always got 64K, in the last row meaning you didn't have to cross someone else's legs to get in and out. It was practically a private cabin. She liked that seat so much that she once declined an upgrade to F so she could keep it. (It didn't help that on a previous upgrade to F she got food poisoning, moral, never eat the fish).
There's nothing on the 777 or 787 that can even begin to compare. (Haven't flown their A350s so can't comment on that).
