Hi everyone…have a question about transiting in NRT, which I’ve done a few times, but pre-COVID. So probably different.

We’re looking to book SFO-SIN in June, which would transit in NRT - there’s a couple of options I’m looking at - but either way, it’s the standard North American arrival bank connecting to the evening departure - would likely come in on either NH or AC connecting to the NH or possibly SQ flight. So either way, ~3 hour layover. Same route on the way back - standard morning departure with ~3 hour connection back to the North America.

My understanding is there is no transit requirements - I just need to meet the SIN and US entry requirements for each direction. However, I have no eligibility to enter Japan at this point. Fine, assuming everything goes well. Obviously a different story if there is some sort of delay causing me to miss a connection, or worse, last minute cancelation to SIN. I’m more concerned about the flights to SIN - as less options than coming back to NA.

In the odd case we misconnect, and they are unable to rebook on another flight, what happens? I understand the terminal is not open overnight, and as I said, we can not enter Japan. I suppose if the issue is known on the ground before departing US/Canada, they could rebook us another way, or next day. But if that isn’t the case, what would happen? Maybe Im worrying over nothing - odds are that there would be multiple others misconnecting if we are, but just trying to be prepped.

Appreciate any insight.
