Travelers should bring a hard copy of their vaccination documentation to show screeners at the gate prior to boarding and/or upon arrival in Hawaii. Screeners will review and verify the vaccination documents, match photo IDs, name, and DOB, as well as confirm that the attestations are signed.
Children under 5 years old are not required to test and will not be quarantined if traveling with an adult who has a pre-travel test exception or a vaccination exception.
Anyone arriving in the United States with valid testing from another country is not automatically accepted for travel to Hawaii.
A test has to be administrated from an approved facility in the United States making it technically impossible to go on a through flight from a foreign country without stopping for a day or more to get the test and avoid quarantine.
There are approved facilities in Japan making it the only international exception.
