Korean Air First Class "Kosmo Suite 2.0"
We flew First Class on Korean Airlines A380 from Seoul to New York City earlier this year (thanks largely to Chase Sapphire points) and loved it.
I noticed today that the already amazing seat is getting an upgrade - the Kosmo Suite 2.0 will have fully-closing doors that are apparently see-through only from inside the suite. It also looks like they raised the height of the partition for even more privacy. The partitions can be raised and lowered and yes, I had a lot of fun playing peek-a-boo / Bye Felicia! with Kelly during the trip :)
We have the big Japan trip coming up next spring, but we're doing ANA and JAL for that trip so we won't be able to check this out anytime soon.
