On December 2, 2021, the Center for Disease Control (CDC) announced that all individuals traveling into the United States two years or older via air travel regardless of vaccination status or citizenship will be required to take a COVID-19 viral test and show a negative result to the airline, no more than one day before boarding a flight. This new requirement is effective on December 6, 2021, at 12:01 am (ET).
Those who recently recovered from COVID-19 may instead travel with documentation of their recovery, alongside a letter from a licensed healthcare provider or public health official stating that they are cleared for travel. The positive COVID test result should be from a sample taken no more than 90 days before the flight’s departure to the United States.
