I'll be flying to Hawaii from Vietnam, connecting in Narita for 6 hours. However, the fares are separate from Vietnam to Narita (VN airlines) and from Narita to Honolulu (UA). Appreciate if anyone can advise if I need to claim the baggage and check in again, and 6hrs is sufficient for such process given the flights are separate? (if the 1st flight delayed then can be a problem right?) and if the baggage fee is calculated separately for the 2 flights?
Great thanks if you can help.
