I found the service to be excellent overall. We flew ORD-ICN and ICN-ORD on the 747 ( upstairs there, main level back ) which has the older lie flat at an angle seats, similar to AF J, which were comfortable. Two meals, both with western and korean dish choices, both very good. Flight crew was very attentive the entire flight, and very accommodating with our infant on the way back ( brought my wife and mine meals out separately so one of us could eat while the other was attentive to the baby, and let us stretch out and play with him on the floor of the second J cabin which was nearly empty ).
