I'm arriving into LAX from NRT on JAL on 1/2, and then connecting to DCA on AS. I'm guessing I'll be coming into TBIT an heading out of terminal 6. I've read conflicting reports and want to know what to expect. Will I have to exit and reclear security, or does the new airside walkway between TBIT and terminal 4 mean I can stay airside after clearing customs? I have global entry, so am hoping the whole process won't be too much of an ordeal. We have about 2.5 hours connection time. Thanks for any input!
