We flew the reverse route (ICN to SEA). The aircraft was swapped to the 2-3-2 layout with old Prestige Sleeper suite rather than Apex suite. When we booked - it was on Apex. It seems like it will be setup for a while. We were shopping for SEA to ICN flight in late Sept and it is still showing old Prestige Sleeper 2-3-2.

Seats are true lie flat - not angle fla, but not Apex Suites (ala JAL).
