I would like to add my good feelings about Korean Air. I just returned from a trip to Japan, and flew JFK-ICN-NRT and NRT-LAX on Korean Air for the first time. Great service, got a bump to first on the return and loved the bibimbap for lunch!
I also requested, and got to sit in my "dream seats" on a 747-400. Upstairs on the way over, and 1-J on the return. As someone else stated, since you are up in the nose, 1-J is like sitting in the cockpit. Incredible.
