Are the long haul Y seats similar to Y+ on JAL in terms of support/slide action? I haven't had the chance to try the long haul Y in CX yet. I have a feeling they're going to mimic Y+ on JAL where they give some J amentities, have a small leg rest and foot rest.

It would be great if they could do a Skycouch concept like Air New Zealand, though I doubt if Y+ will ever be empty enough to have an entire row to yourself.
