Close connection at ICN
We are flying from Atlanta to Bali and connecting in ICN from Delta to Korean Air. We'll have just shy of 90 minutes between flights. We are planning to check a bag, but I understand from Delta that if I show my Korean Air ticket in Atlanta we'll be able to check that bag all the way to Bali. I'm trying to figure out how difficult/risky this is. Will we have to clear customs etc in ICN? Any insight would be much appreciated. thanks!
