A representative from Virgin Atlantic told ABC News it will implement a new protocol for United Kingdom travelers that mandates a COVID-19 test before boarding flights to the U.S.

"With the health and safety of our customers and people always our number one priority, we will require all travelers to present evidence of a negative LAMP or PCR COVID-19 test, taken up to 72 hours prior to departure, including on-site at the airport," the representative said in a statement.

The new requirement goes into effect on Dec. 24.

The change comes after New York Gov. Andrew Cuomo called on international airlines to test passengers for the coronavirus before getting on a plane to the U.S. A variant of the virus has been discovered in Britain and prompted several countries to suspend travel from the U.K.
