Effective January 26, 2021 all airline passengers to the United States ages two years and older must provide a negative COVID-19 test. The test must be viral (PCR or antigen) and taken within three calendar days of travel,  to determine if the passenger has an active COVID-19 infection. The results must be presented to the airline in an electronic or paper format. Alternatively, travelers to the U.S. may provide documentation from a licensed health care provider of having recovered from COVID-19 in the 90 days preceding travel. If the passenger does not meet these requirements or chooses not to take the test, the airline will deny access to the aircraft. It is recommended that passengers traveling to the United States monitor the CDC official website and follow their recommendations on quarantine and local and state requirements related to travel.
