thank you. i was concerned the gate agent at LAX can only see my NRT destination and assume i'm trying to enter japan, so i was just planning to show both my UA and ANA itineraries when checking in?
i'm supposed to arrive 230PM in NRT at T1 and fly out in T1 as well at 615PM, so that should be easy..
