If you frequently travel to the United States by air or are about to do so, remember that by instructions from the U.S. Centers for Disease Control and Prevention (CDC) beginning January 26, all air passengers two years of age or older must present a negative COVID-19 test result to enter this country.

According to the CDC, people who are traveling to the U.S. must have a PCR or antigen test within 3 days of their flight departure. Including U.S. citizens and legal permanent residents.

Laboratory results, either on paper or an electronic copy, should be submitted to the airline. If you have recovered from COVID-19 in the last three months, you must also submit your recovery documentation to the airlines and a letter from your physician indicating that you are authorized to travel. If your recovery is longer, you should only take the test and prove that you have tested negative.

It should be noted that if a passenger does not provide documentation of a negative test or recovery, or chooses not to take a test, the airline is required to deny the passenger from boarding, CDC says.

In the event that the passenger was one of those who received the vaccine, according to CNN, this new rule must also be complied with.

On the other hand, those with private airplanes are not exempt from this requirement, since it applies to both commercial and private flights.

CDC spokesperson Caitlin Shockey told CNN that people who booked a connecting flight must comply with this new preventive measure, as well as those with a longer connection, or if their flight was delayed beyond the three-day window.

Although if you have a trip outside the U.S. for less than three days, you can take the test and use it on your return.
