The US government does not intend to impose COVID-19 screenings for passengers traveling from Britain after the emergence of a highly infectious new coronavirus variant there, people briefed on the decision said. White House coronavirus task force members backed requiring negative pre-flight tests after a meeting on Monday, but the Trump administration has decided not to take any action for the time being, the people said. Much of the world shut their borders to Britain after the discovery of a mutated variant of the novel coronavirus, though the European Union recommended on Tuesday that members roll back sweeping closures to allow some travel. Canada is implementing enhanced measures to screen travelers from Britain, including those arriving from other nations, its public safety minister said on Tuesday. The three airlines that operate flights from London to John F. Kennedy International Airport – British Airways, Delta Air Lines and Virgin Atlantic – voluntarily agreed to a request from New York Governor Andrew Cuomo that they only allow passengers who test negative to fly. The Trump administration has repeatedly refused to issue mandates for many federal COVID-19 safety policies for air travel, making only strong recommendations on issues such as mask wearing. President-elect Joe Biden has vowed to mandate masks in interstate air, bus and train travel after taking office on Jan. 20. The White House in August scuttled an effort to require airlines to collect contact tracing information from US-bound international passengers, Reuters reported. The White House in July rejected a proposal to require facial coverings at US airports, train and transit stations and onboard airplanes, trains and transit services and earlier dismissed proposals to require temperature checks of airline passengers.
