Anyone flown longhaul with Korean Airlines?

[evenhope]

So far cheapest quote for NZ flights are with Korean Airlines via Seoul. Antone flown with them?

Yup. I've flown with them many a time.
Theirs is the cheapest route from Nagoya home to London, also via Seoul.
I've never had any problem with them.
They always give good service, are helpful and the food is fine. (Dinner is always a choice of a western style meal or a korean dish called bibimba)
They definitely aren't the best airline in the world, but I'd fly with them again.
However, I've never used them with kids so I can't comment on that.
