I think this is fairly a good price, others:
Korean Airlines $1446.41
Air France $1592.57
Malaysia Airlines $1612.72
KLM Royal Dutch Airlines $1663.17
China Southern Airlines $1686.47
Cathay Pacific Airways $1783.24
Comes with free stay-over at Seoul and fly with A380.
Also STA is having a $99 lay-by, the rest is payable 5th December.
Cheers.
How many 1000's of kms does it add to your trip flying via Seoul ?
