I’m thinking about booking a frequent flyer ticket in business class on this itinerary: SGN-NRT surface -HND-HNL. The schedule provides 6 1/2 hours between flights. Aside from the hassle of changing airports, are there any issues?
that’s plenty of time to make that trip. just make sure you have your Visit Japan Web registration all set so you can enter the country. Biggest obstacle is finding award availability but maybe you already have that sorted.
