Asiana Airlines is the one to fly on if anyone is planning to fly to Asia. Their flight crew provides excellent service and very customer focused. The US airlines pales in comparison

Maybe next time I would like a seat NOT next to the bathroom :p

It was warm in the cabin and the plane did not have individual vent controls for the air which means we remained warm for the duration of the 11 hour flight. The food was ok but did not compare with the food we had on Asiana on a previous flight to Incheon in 2013. That was disappointing.

The aircraft between Incheon and Hkg had the most uncomfortable seats. Insufficient padding did not recline etc.

International customs at SeaTac is awful! Huge waits. Much better in Asia.
