The new rules come on the heels of a recent lifting of pre-flight test requirements, and are part of a general easing of COVID-19 restrictions as the U.K. starts to treat the virus as endemic. 

“To show that this country is open for business, open for travelers, you will see changes,” Johnson told broadcasters Monday in a pooled interview. “People arriving no longer have to take tests” if they are double vaccinated, he said. 

The change will lower the cost of travel and give consumers more confidence their plans won’t be upended at the last minute by yet another rule change or a positive test. Airlines, which have sought to lift all testing requirements—are sure to get a boost, as are hotels and restaurants. 

Carriers welcomed the government’s decision, which comes ahead of the half-term school holidays next month, followed by spring break and the busy summer season.

“We believe testing for travel should now firmly become a thing of the past,” said Johan Lundgren, the chief executive officer of discount carrier EasyJet Plc. “We now look ahead to what we believe will be a strong summer.”

Airline shares fell steeply amid a broad market selloff. EasyJet was down 4% at 1:28 p.m. in London. British Airways owner IAG SA lost 6% and Irish discounter Ryanair Holdings Plc was off 5.5%. 

Omicron setback

Travel was starting to come back in the fall, just before the rapid spread of the Omicron variant reversed a loosening of border policies for those who were inoculated. 

The number of international flights currently scheduled from the U.K. during the February half-term holiday are up sixfold from a year ago but remain 41% below 2020, before initial European lockdowns took effect, according to data from aviation analytics firm Cirium. Spain is the most popular destination followed by Ireland.

“This is a landmark day for passengers, businesses and U.K. Plc,” said Tim Alderslade, who heads the Airlines UK industry lobby. “Nearly two years since the initial COVID restrictions were introduced, today’s announcement brings international travel towards near-normality for the fully vaccinated, and at last into line with hospitality and the domestic economy.”

U.K. Transport Secretary Grant Shapps is expected to give more detail on the new policy in a statement to the House of Commons on Monday. 

The U.K. has been easing its “Plan B” COVID restrictions that were implemented across England in December when the Omicron variant spread quickly through the population. 

People are no longer being asked to work from home, and rules forcing people to wear face masks in shops and on public transport will be dropped from Jan. 27. Mandatory COVID passes for businesses will also end this week.
