At long last, the State of Hawaii is putting in place a vaccination exemption to the mandatory 10 day quarantine. Starting July 8th travelers fully vaccinated (plus two weeks) will be able to bypass the mandatory 10 day quarantine. You will still need to set up your Safe Travels account and upload your vaccination card. However, if fully vaccinated, you can skip getting the onerous pre-travel test.
Please note, per the official website you must have received your vaccination in the United States (no exemption for those vaccinated internationally).
Should you or some in your travel group not be vaccinated, you can still pre-travel test to avoid the mandatory quarantine. Please make sure to follow the official instructions closely. Do not board your final flight without your test results in hand.
For much more information and the most accurate details, please see the official Hawaii Covid Travel website.
