Denied boarding, gate dragon was saying I could be deported (despite ticket to SFO) and "the border could close and you'd be stuck", they also said during COVID they have multiple boarding denials a day (someone was even pulled off plane today....) due to confusion and misunderstandings about docs checks and rules. They made it clear it wasn't United/their fault and rather the government rules - did confirm Guam was good of course as a destination, except that it was full - on the bright side, still a fun day in the lounges tho

Happy to be the lab rat :P Now realizing I can do a lot better PQP/MR's and maybe 25 hours of travel isn't worth it during COVID especially. Cheers guys. For reference, I was not questioned at check-in, just at boarding. Appreciate the insights and all - hopefully will get to go through NRT on some tourism post-covid
