Delta will require new pre-departure COVID-19 testing for all customers traveling from the U.K to the United States. Delta's joint venture partner Virgin Atlantic is also implementing this new requirement. 

Beginning December 24^th, all passengers flying from the United Kingdom to the United States, or transiting through the United States, are required to show proof of a negative PCR or LAMP COVID-19 test taken less than 72 hours prior to departure. Passengers will be required to show proof of the negative test result prior to boarding their flight from the UK. Passengers originating travel outside of the U.K. and transiting through the U.K. are exempt from this requirement.

We recommend that passengers get tested prior to arrival at the airport. For additional information, please visit the list of U.K. approved testing providers to find a testing center prior to travel. Testing is also available at London-Heathrow (LHR) airport; more information is also available for LHR airport testing and to schedule a test. Travelers should arrive four hours early to the airport to allow extra time to get your test if you have not done so in advance.

Please refer to the Travel Requirements & Restrictions Map on delta.com for the latest updates to these policies.
