I'm looking at flights and I see there's one option with a 2 hour Layover between two international flights thru Narita. Both flights are the same carrier. Normally I like to give it a little more for international flights and the one coming in is after 13 hours. I assume it'll be in the same area and I don't have to go through security, but if there's a chance, I'd like to know upfront. Any thoughts... too tight or it'll work fine?
