We are Myanmar passport holders, me and our family are planning to visit Japan and Korea this April. We're planning to book a connecting flight from Japan to Korea, and then to Yangon.
Is it OK for our baggage check through from Tokyo (by Korea Airline) to Seoul (by Vietnam Airline) to Yangon? Is it also ok for stay 12 hours layover in Seoul Incheon airport?
I booked tickets separately, Myanmar to Seoul (round trip ticket by Vietnam airlines) and Seoul to Tokyo (round trip ticket by Korea airlines)
