ORD-NRT-CGK
I have a similar itinerary to the poster above, but worse due to the change in airlines:
UA 881 ORD-NRT, arriving 4:30 PM
JL 729 NRT-CGK, departing 6:50 PM
How much time will it take to claim luggage from UA, navigate to JL's terminal, and re-check luggage there? I'm sure 2 hours is more than enough, but deck is stacked against us as far as arriving on time (UA + ORD in winter).
