I came in at almost midnight. Was processed through at the airport very quickly. Got to my "test and go" hotel after my covid test around 1 am. Was told 4 hrs. More like 8 hours. I shouldn't complain honestly. But about 22 hours from the US I was more than tired waiting on results but honestly that wasn't that bad
But this is ONLY through Japan Airlines. They all do their own thing so I'd just check on it to keep up to date. They should email also if things change. Keep an eye out
That's what I figured but it didn't and they just changed this yesterday. That's when I got the updated email. I still had planned to get tested the day before anyway even though it costs me to get a quick result PCR test
