Covid-19 Travel Protocols

International Travel During Covid-19:

Currently, the U.S. requires proof of a negative COVID-19 test for all air passengers arriving from outside the United States, including U.S. citizens and Legal Permanent Residents, even if fully vaccinated.  International arrivals must be tested no more than three days before their departure and will need to present the documentation of a negative test result or documentation of having recovered from COVID-19 to the airline before boarding the flight.

What You Need to Know

  • If you plan to travel internationally, you will need to get a COVID-19 viral test (regardless of vaccination status) before you travel by air into the United States. You must show your negative result to the airline before you board your flight.
    • Fully vaccinated: The viral test must be conducted on a sample taken no more than 3 days before the flight’s departure from a foreign country if you show proof of being fully vaccinated against COVID-19.
    • Not fully vaccinated: The viral test must be conducted on a sample taken no more than 1 day before the flight’s departure from a foreign country if you do not show proof of being fully vaccinated against COVID-19.


The State of Hawai’i will align with federal international requirements. There will be no additional State of Hawai’i requirements for passengers flying directly into Hawai’i from an international destination. The airlines will screen passengers prior to their departure to the U.S. International passengers entering the U.S. from another state or territory will be treated as domestic travelers when entering the State of Hawai’i.

For international travelers coming to the State of Hawaii, only tests from Trusted Testing Partners will be accepted for purposes of bypassing the State’s 10-day traveler quarantine.

Trusted Testing Partners: If a trusted testing partner is not available in your area, contact your airline or airport in connecting cities prior to booking your flight. Many locations offer Rapid Covid Testing (for a fee) that can be used to complete your travel to the State of Hawaii.

Note: Los Angeles International Airport (LAX) also offers Rapid COVID Test by appointment and walkthrough (depending on demand). LAX’s COVID-19 testing lab is certified as a trusted testing partner by the State of Hawaii and tests are eligible to meet current travel requirements to the state. Tests are offered for a fee ranging from $80-$199 and depending on the test, results are made available anywhere from less to 1 hour, 3-5 hours or up to 24 hours.

The CDC and WHO recommend that individuals do not travel unless they are fully vaccinated. We recognize there are global vaccine inequities and some individuals may be unable to upload proof of vaccination information. A negative covid-test is an alternative for individuals traveling from countries, not on the prohibited entry list.
