Hello, CJ! The train amongst terminals is effectively-marked and simply accessible, and even though it requires about 7 minutes, I would budget 15 in the event you require to wait + some time to receive to your teach. I would give myself not less than an hour amongst landing and another flight's takeoff for that transfer, so long as my baggage ended up checked on to my last spot (which they might be, if those two are on the identical reserving), but a lot of that point will just be for boarding. Delight in Vietnam!~
I don't think that Korean Airlines provides absolutely free accommodation for layovers, unfortunately, however you will discover a lot of excellent sites in 토지노 stay in Seoul that could set you within the midst of each of the motion & near the primary points of interest through your extensive layover.
In case your bag isnt staying checked onwards by your airline as well as your layover is right away, Then you definitelyll will need to claim & re-Check out your bag(s) three hours or less before your flight.
