Travel Guidance for COVID-19

CDC Travel Guidance Within the United States

Anyone who is fully vaccinated against COVID-19 can travel within the United States without needing a COVID-19 test result or to self-quarantine after travel. We must all still take precautions while traveling, including wearing a mask, avoiding crowds, socially distancing, and washing hands frequently.

CDC Order Requiring Testing Before International Travel 

To reduce introduction and spread of new variants of SARS-CoV-2, CDC issued an Order effective January 26, 2021. It requires all air passengers arriving to the US from a foreign country to get tested for COVID-19 infection no more than 3 days before their flight departs and to provide proof of the negative result or documentation of having recovered from COVID-19 to the airline before boarding the flight. For more information on this testing requirement, select the tab below.

Know when to delay your travel

Travelers with a known exposure to COVID-19 should delay travel, quarantine themselves from other people, get tested, and monitor their health.

Check travel restrictions at your destination

State, local, and territorial governments may have travel restrictions in place, including testing requirements, stay-at-home orders, and quarantine requirements upon arrival. To help slow the spread of COVID-19, it is important that you follow these travel restrictions. 

For up-to-date information and travel guidance, check the state, territorial, tribal and local health department where you are, along your route, and where you are going. Prepare to be flexible during your trip as restrictions and policies may change during your travel. 

Travel can increase your chances of getting COVID-19. Staying home is still the best way to protect yourself from COVID-19. Stay home if you are sick or if you have been around someone with COVID-19 within the past 14 days. For more information on traveling review the CDC’s travel guidance.

Domestic Travel Guidance

Travel increases the chance of getting and spreading COVID-19. Fully vaccinated travelers are less likely to get and spread COVID-19. CDC recommends delaying travel until you are fully vaccinated. All travelers should follow CDC recommendations for vaccinated and unvaccinated people.

In order to be considered fully vaccinated before traveling for the holidays, people should get their first dose of vaccine by the following dates:

  • Thanksgiving (Nov. 25): Moderna by Oct. 14, Pfizer by Oct. 21, Johnson & Johnson by Nov. 11
  • Hanukkah (starts Nov. 28): Moderna by Oct. 17, Pfizer by Oct. 24, Johnson & Johnson by Nov. 14
  • Christmas (Dec. 25): Moderna by Nov. 13, Pfizer by Nov. 20, Johnson & Johnson by Dec. 11

Check to see if there are a lot of COVID-19 cases at your destination.

The more cases at your destination, the more likely you are to get infected during your travels.

Are you or someone you live with at a higher risk for COVID-19?

If you become infected while traveling, you may become very sick while you are traveling. You can also spread the virus to your loved ones when you get home. 

Check to see if your destination has local requirements or restrictions for travelers.

Some places have requirements for travelers, like quarantining for 14 days after you travel. Check state, territorial, tribal, and local public health websites for information before you travel. 

If you are traveling by air, make sure you social distance from others in the terminal or on the trains to different terminals.
