We're planning on flying ORD-NRT on JL, arrives in NRT at 14:55. There's a NRT-ICN on OZ at 16:20, so it would be a 1:25 connection time. From what I've read, 1:25 should be sufficient. However I'm assumming that we won't be able to check-in online for the NRT-ICN. Is 1:25 still enough time to find an OZ connection / transfer desk and check-in?

JL do have an interline aggrement with OZ, but it's probably too risky to try and check a bag at ORD?

I believe we will arrive in T2 International and we will need to take a shuttle bas to T1 Internation (South) which takes about 10 minutes.
