There is hardly an airline left in the world that doesn't provide reclining seats on intercontinental flights in First and/or Business class, unless it provides beds.
Now, as far as I know..., people have been sleeping fully flat for millennia. And not at reclines of hundred-umpteen degrees, as all those ads depicting smilingly sleeping travellers, half sitting, half lying down, mostly in impeccably ironed dress shirts or blouses, imply.
Since I have never tried such seats myself, I would like to know whether these reclining seats are really relaxing/enable sound sleep, or rather let one wake up feeling cramped.
Frequent travellers, over to you...
Btw, this is not an attempt in any way to support BA's new Club World. If I remember correctly, that too has already been criticized (for its head-to-foot layout, among others) in this forum.
