During the height of the coronavirus pandemic, airlines implemented dozens of measures to improve the cleanliness and safety of their planes, including installing HEPA filters and blocking middle seats. Fortunately, by 2022, the global situation has significantly improved, and the restrictions that were previously in place for both domestic and international travel have been lifted. Here are some new updates about if airlines require COVID test for domestic flights in 2023.


Do I need a COVID-19 test to fly domestically in 2023?

The Centers for Disease Control and Prevention (CDC) has updated its recommendations, stating that vaccinated travelers flying domestically do not need to be tested prior to travel. However, unvaccinated travelers flying within the United States should be tested one to three days before departure.

In addition to that significant change, major US airlines no longer require passengers to wear masks in flight or at the airport. However, some international destinations will still require passengers to wear masks. You can check the destination travel health restrictions by destinations provided by CDC to update the latest policy. 

Recently, some regions that suffer most seriously from the pandemic, which are China, Hong Kong, Ma Cau, have lifted arrival tests at the airport since February, 2023 so it is now not required to have a COVID test when you travel both nationally and internationally.

So what documents do I need when traveling domestically?

In the United States, you need a valid U.S. government-issued photo ID or a passport from your country of origin to travel through security. You must show that the name on your boarding pass matches the legal name on your unexpired government-issued ID.

Do I need to be vaccinated to travel?

The USA as well as some other countries in the America has lifted restrictions for covid test and vaccinations (except for Costa Rica), so you don’t need to be vaccinated before traveling. 

Can I travel if I had COVID-19? 

Yes, you can travel once your isolation period is over. However, until it is safe to remove your mask around others, you should wear a high-quality mask or respirator the entire time you are indoors. If you will not be able to wear a high-quality mask or respirator when around others indoors for the duration of your trip, do not travel on public transportation such as airplanes, buses, and trains. Learn when you can travel and how to protect others while on the road.

If you have had COVID-19 in the last 90 days, you should seek specific testing recommendations before traveling.

Other travel recommendations and requirements for domestic and international travel should be followed.

What happens if there is a sick passenger on an international or domestic flight?

Pilots must report all illnesses and deaths to the CDC before arriving in the United States, according to current federal regulations. If a sick traveler has a contagious disease that poses a risk to others on the plane, the CDC collaborates with local and state health departments, as well as international public health agencies, to contact exposed passengers and crew.

When booking your ticket, provide the airline with your current contact information so that you can be notified if you are exposed to a sick passenger on a flight.

For more information, see the CDC webpage Protecting Travelers’ Health from Airport to Community: Investigating Contagious Diseases on Flights.

Can I be fully refunded if I have COVID after booking the ticket?

Recently, there is no longer a special support to cancel the flight because of COVID-19. Therefore, if you cancel your flight because of COVID-19, you should follow their cancellation policy and instructions.


What should I do to protect myself and others from COVID-19?

CDC has some recommendations when you travel to keep you safe from the pandemic:

  • Get up to date with your COVID-19 vaccines before you travel.
  • Consider getting tested before travel.
  • Follow CDC’s recommendations for wearing masks in travel and public transportation settings.
  • Get tested after travel if your travel involves situations with greater risk of exposure such as being in crowded places while not wearing a high-quality mask or respirator.

Travel is much safer now

COVID-19 exposure risk is reduced when air filtration systems and masks are used, according to studies.

According to the most recent research, aircraft cabins are among the safest public indoor environments. According to a recent study conducted by the U.S. The Department of Defense (DOD) agrees that the risk of COVID-19 exposure on board our planes is nearly zero due to advanced air filtration systems, required mask wear, and meticulous cleaning protocols.

According to Harvard T.H. Chan School of Public Health researchers, “there has been little evidence of onboard disease transmission” since airlines implemented these measures in spring 2020. Their report states that when “highly effective” ventilation systems are used from boarding to deplaning, as is our practice at United, the risk of exposure is lower than that of activities such as grocery shopping and dining out.

According to the DOD study, even when the plane is full, only 0.003% of infected air particles enter the breathing zone of seated, masked passengers.
