Hi - has anyone flown through Narita connecting to Manila or other Delta outbound flight lately? I have a 70 minute layover between my Delta MSP to NRT arrival and my NRT to MNL departure. I know I have to go thru the Japan transit security line (carry on and passport check), does anyone know if 70 minutes is good enough (same DL ticket), is there a business class transit security line? Thanks in advance. Delta today put a note on my flight saying I should call my local travel office since the layover timing was at risk for connecting flight.
