IMHO one big miss for this new product is not having a real divider and curtain between the new Premium Economy and regular Y, which is something I believe the majority of airlines with a real Premium Economy product (BA, VS, QF, CX) do. I'm assuming LH did this to preserve the amount of space lost. However, having flown long haul several times on CX in Premium Economy, having a divider and curtain makes a big difference-- it creates a separate cabin that is quieter and more private, and reduces the amount of foot traffic going past your seat.
