ข้อดี: for the flight from Seoul to Singapore, the flight was superb. In-flight services was perfect. food was excellent and the air stewards and stewardess were all very helpful and full of smiles.
ข้อเสีย: Check In process at Seoul Counter. the check-in was stressful. the ground staffs insist on using Check-in Kiosks provided even when it was not working as it should be. Ended up being bounced from one staff to another.
