Travel Guidance

Updated March 18, 2022

Significant Updates

  • 3-21-22: Updated to align with CDC statement that persons who have tested positive for COVID-19 may not travel for a full 10 days after their symptoms started (or after the date of the first positive test if they had no symptoms).

COVID-19 remains a threat to our local and global community. Travelers should make sure that they are up to date with their COVID-19 vaccines, meaning they are fully vaccinated and received their booster dose, if eligible, prior to travel. Travelers should continue to take precautions to reduce the risk of COVID-19 such as masking, physical distancing, and hand hygiene. Help keep California and Los Angeles County open and our communities healthy by following the CDC travel guidelines and the guidance below.

When considering travel within or outside of California or internationally, Los Angeles County Department of Public Health asks that all travelers do the following:

  • Do NOT travel if you or any of your traveling companions:
    • Have symptoms of COVID-19 (even if you recovered from COVID-19 within the past 90 days or are up to date with your COVID-19 vaccines).
    • Tested positive for COVID-19. Do not travel until a full 10 days after your symptoms started or after the date your positive test was taken (if you had no symptoms).
    • Have been in close contact with someone with COVID-19 and have not ended quarantinei
    • Are waiting for the results of a COVID-19 viral test.

    For more details on when a person should not travel, see the CDC’s When Not to Travel guidance.

    I Close contacts that end quarantine early or are exempt from quarantine:
    • If you have met the criteria to end quarantine early (after 5 days), it is strongly recommended that you avoid travel for the full 10 days after your last exposure. If you must travel during Day 6-Day 10, you must have no symptoms of illness and should monitor your health and wear a highly protective mask around others.
    • If you are exempt from quarantine and have no symptoms, there are no travel restrictions. However, you should wear a highly protective mask when you are around others and monitor your health for 10 full days after your last exposure to the person with COVID.
    • See Quarantine and Other Instructions for Close Contacts at ph.lacounty.gov/covidquarantine.
  • Delay travel until you and all of your traveling companions are up to date with your COVID-19 vaccines.
    Booster doses are not required to travel, but they are strongly recommended if you are eligible.

    COVID-19 vaccines are widely available across LA County. See Get Vaccinated for more information.
  • Take extra precautions if you or any of your traveling companions are at high-risk of severe illness from COVID-19. Consider checking with your healthcare provider for more specific advice about travel based on your health and underlying medical conditions. If you haven’t already, be sure to get up to date with all of your COVID-19 vaccines.
  • Wear a face mask that fits and filters well during travel.
    • Wearing a mask over your nose and mouth is required in indoor areas of public transportation (including on planes, trains, and other forms of public transit), and indoors in any transportation hubs (such as airports and stations).
    • It is strongly recommended that you wear a mask in indoor public places, especially if you (or your traveling companions) are immunocompromised or at high risk for severe disease or if you are traveling in an area where the COVID-19 levels are high.

  • Monitor for symptoms for 10 days post travel. If you develop symptoms, stay home and get tested. Visit ph.lacounty.gov/covidtests for local testing resources.

Additional travel requirements and recommendations vary by vaccination status and whether domestic or international travel.

Domestic Travel

  • Plan ahead:
    • Check the current COVID-19 situation at your destination.
    • Make sure you understand and follow all state, tribal, local, and territorial travel restrictions, including proper mask wearing, proof of vaccination, testing, or quarantine requirements.
    • For up-to-date information and travel guidance, check the state, tribal, local, and territorial health department’s website where you are, along your route, and where you are going.

  • If you (or any of your traveling companions) are NOT up to date with your COVID-19 vaccines and you must travel, follow the steps below and CDC Safer Travel Tips for people who are not up to date with their vaccines for additional information:
    • Before travel, get a COVID-19 test* as close to the time of departure as possible (no more than 3 days) before you travel. Only proceed with travel if your test is negative.
    • After travel, you should:
      *Note: If you recovered from COVID-19 in the past 90 days, you do not need to test or quarantine as long as you are asymptomatic.

  • If you are up to date with your COVID-19 vaccines:
    • Before travel, consider getting a COVID-19 test* 1-3 days before travel, especially if you have recently been in crowded spaces and/or you will be gathering with people from other parts of the country. Best to take the test as close to travel as possible and do not travel until you receive a negative result.
    • After travel, consider getting a COVID-19 test* 3-5 days after you return to California.
      *Note: If you recovered from COVID-19 in the past 90 days testing is not recommended, unless you develop symptoms.

International Travel

International travel poses additional risks and even travelers who are up to date with their COVID-19 vaccinations may be at increased risk for getting and possibly spreading new COVID-19 variants.

All international air travelers must adhere to the following federal guidelines:

Prior to boarding a plane from a foreign country to the U.S.

After arriving in the U.S.

  • Get a COVID-19 test 3-5 days after travel regardless of vaccination status. Note this is a requirement for non-US citizens and non-US immigrants who are NOT fully vaccinated and allowed to travel to the U.S. by air through an exception.
  • Quarantine for 5 full days if you are not up to date with your COVID-19 vaccines. Stay home for 5 full days after travel unless you recently recovered from COVID-19.

    Note for Non-US citizens: you are required to quarantine at home or in your hotel room for 7 days if you are not fully vaccinated and you were permitted to travel by air through an exception, (unless you have documentation of having recovered from COVID-19 in the past 90 days). If you are fully vaccinated but not up to date with your vaccines, quarantine is recommended for 5 full days.

For non-US citizens and non-US immigrants who are not fully vaccinated and were permitted to travel by air through an exception: If you intend to stay in the U.S. for 60 days or longer, you must become fully vaccinated against COVID-19 within 60 days of arriving in the U.S. or as soon as medically appropriate, unless you have a medical contraindication or are too young to be vaccinated.

*Persons who have recently recovered from COVID-19. If you tested positive for COVID-19 with a viral test and recovered, you do not need to test or quarantine again for 90 days as long as you do not develop new symptoms of COVID-19. “Recovered” means you are no longer infectious (and have completed isolation). If you had symptoms with your most recent infection, the 90 days are from the start of your symptoms. If you never had symptoms, then the 90 days are from the date of collection of your first positive viral COVID-19 test.
