Not Verified | Seoul to Ho Chi Minh City. I have had to buy 2 flights and pay an 80,000 KRW baggage fee because of the incompetence of this airline, and particularly the website, which does not work. Neither of the two sets of log-in details I was given was recognised, and the first time the website screwed up the date, giving me a flight on the week before. Calling the contact center (in Ho Chi Minh city, by a native Vietnamese speaker) and they could find no details at all of my flight, but said that since they couldn't find the flight details, that I would have to rebuy the ticket. This I did. On the website (Trip.com) there was no details at all about checked luggage, so I assumed the details on the previous flight would be the same. A simple google search reveals the following "Baggage allowance: The maximum weight allowed is 20kg for international flights and 15kg for domestic flights. For hand baggage, you are allowed one small carry-on bag with three sides less than 115cm and lighter than 10kg." Check-in staff at Incheon recognised my position as being just but refused to do anything at all to help, and dumped me with an 80,000 KRW fee. This will be the last won you will get out of me.
