My understanding is that transit is allowed without covid testing (USA is blue category, Vietnam is yellow category, and I'm triple vaxxed), so I should be fine for those flights as I won't need to enter Japan.
However, my question is worst case scenario. What if I make it to NRT and then when I'm there, one of the flights out of NRT is cancelled and I am not able to be rebooked that same day? Does anyone know what happens in this situation since NRT isn't open overnight and I wouldn't be able to enter Japan? Can I stay in terminal 2 airside? How often are flights cancelled and people end up in this situation? I find it strange that Narita isn't a 24 hour airport.
Thanks!
Probably no way to answer this 100%, as so many scenarios can play out, but most likely you will just overnight in NRT. While it's technically not an overnight airport (you can't book a flight connecting overnight), there are times when people have to overnight. It won't be fun, you won't get lounge access, but there will be a section of the terminal blocked off for such situations. The biggest issue is the expired covid test to come back to the US...can you get another one at NRT or would you not be able to and they send you back to Vietnam (i'd personally fight tooth and nail to prevent this). Kind of up to the airline...and flying JL might have it's benefits in this case. Here's a worst case scenario that had possible chaos and definitely a lot of confusion:
