This article surveys frequent flyers and all their suggested amenities at airports. I would actually like to see more seating at restaurants and bars at airports. Most airports have limited seating especially non-international terminals. It seems we are always fighting to find a seat.
I would recommend the Korean international airport as a great place to spend your layover. When we fly Korean Airlines or Asiana Airlines we have a long layover waiting for our flight to China but it is a great place. It has many cultural activities for kids and adults which we would recommend to walk around the large terminal to find different things to do. The food at this terminal is excellent and my wife loves the Korean restaurant. I hope the US airports continue to improve and modernize for travelers.
Passionate for everything related to China travel.
