we just flew ICN/ATL (outbound was iffy on seats, so we opted for ATL/NRT last-minute)
2 NW pax were put up front with us, even tho there were tons of seats in back (wasn't that nice?!)
Inter Asia KE business class is only so-so--we just used miles for ICN/DPS and the seats/food are average at best (Airbus 330 whale--old fold-out metal footrest, fabric seats, skinny pillows and static blankets, minimal service)
