England is expected to open its borders to allow the U.S. and E.U. travelers who are fully vaccinated against coronavirus to enter without the need to quarantine.

The plans, which would be a boost to the aviation and tourism sectors, are set to be discussed by ministers on Wednesday.

Conversations are also expected between Whitehall officials and the devolved administrations on whether the change would apply to England only, or all four nations of the U.K.

The changes are expected as soon as next week, while countries outside the E.U. and U.S. could be allowed inbound quarantine-free travel at a later date.

It comes after aviation firms claimed a trial has demonstrated the U.K. can safely exempt fully vaccinated U.S. and E.U. visitors from self-isolation.

Heathrow Airport, British Airways and Virgin Atlantic said their 10-day pilot scheme proved the vaccination status of travelers can be efficiently and accurately checked away from the border.

Around 250 fully vaccinated passengers on selected flights from New York, Los Angeles, Jamaica and Athens earlier this month presented their credentials using paper or digital formats before boarding the plane.

Some 99 per cent of their documents were verified as authentic, with just two passengers’ credentials rejected.

In one case there was a discrepancy between the name on the vaccine card and the name on the passport, while another involved someone who had been fully vaccinated less than 14 days before travel.

The Department for Transport has committed to a formal review of its rules for arriving travelers before Sunday.

Since July 19, people arriving in the U.K. from amber list locations, such as the US, have had to have received both doses of a vaccine in the U.K. to avoid the requirement to self-isolate for 10 days.

The rules exclude those who have been inoculated elsewhere in the world.

BA chief executive Sean Doyle said the trial provides “the evidence the Government needs” to allow fully vaccinated visitors from low-risk countries to enter the U.K. without self-isolating.

He went on: “The U.K. needs to safely reopen its borders as soon as possible to ensure loved ones can reunite, business can thrive and global Britain is able to take advantage of the U.K.’s world-leading vaccination programme.”

His counterpart at Virgin Atlantic, Shai Weiss, warned that continuing the U.K.’s “overly cautious approach” towards international travel will harm the economic recovery from the virus crisis and put half a million jobs at risk.

He claimed the trial shows airlines would ensure an easing of the amber rules is “implemented smoothly at pace”.

Heathrow boss John Holland-Kaye said: “The vaccine has been a miracle of science, and these trials have shown that we can allow fully vaccinated passengers from the E.U. and U.S. to visit the U.K. without quarantine.

“There is now no reason to delay with rolling out the solution from July 31.”
