They gave us a 30 minute window to transfer in Seattle. We missed our connecting flight to Seoul and had to take a later flight. They then lost our luggage in this process. We had to come back to Ho Cho Minh City airport three different times to check on the status of our bags. It took us over 24 hours to get our bags back and multiple taxi fares. Horrible experience.
