I flew both Boeing 747s and 777s in J.
Seats at the 747s are definitely in the "ancient" side -- legroom is around 48" with a legrest and a small personal TV
(no AVOD, just repeated programs). Boeing 777s have a much better seat with 52" of legroom and more lumbar support. I will fly the SFO
Food is really nice on OZ
... you can expect a full five course main meal with canape, appetizer and salad, main course, cheese and fruit plate, and then dessert and tea/coffee. The Korean bi-bim-bap is nice as well... but only for the ones with more Asian taste in food.
Entertainment is only average -- classic PTV at most.
Service is good -- Asiana F/As are pretty and friendly... they are not as warm as CX
, but they are still fine. If you need anything, just press the call button. I find them not making many beverage rounds in between, but call buttons will be responed with smiles.
Amenities -- no amenity kit, but slippers and eyemasks. Amenities such as toothbrushes, shaving kits, mouthwash... are available in the bathroom. Sort of like SQ
If the price is right, it is not a bad option.
I rate it above EVA business class, but not as good as CI
