Staff Seattle went out of their way to help me at each step of the way. Also helped me to change my return. I try to use Asiana for Asia to US. Great in all ways.

Korean Airlines slow customer service

Feb 12, 2019

Good job

Feb 7, 2019

The food was quite good,and the service was great. On the long flight the movie selection was quite extensive,and made it easier to endure the long flight.

Feb 6, 2019

The food was good, but it could have been better. It was a little inconsistent between airlines. The same goes for the seating, but all in all I would travel with the same airline again.
