LONDON • Families and friends were overjoyed at London’s Heathrow Airport on Monday after a travel rule change meant they could reunite after 18 months of pandemic separation.

“Very, very excited. It means the world,” said Sue Blake, as she waited to greet her son, daughter-in-law and grandson who had flown in from New York and who she last saw two years ago.

“It’s a big chunk of his life and I’m so thrilled for him that he can come here,” she said of the eight-year-old.

Watching the hugs and tears in the arrivals hall, Heathrow’s boss urged Britain to remove barriers to travel, not add to them, amid speculation that the government was poised to impose more rules.

“Let’s just make it easier now for people to travel,” Heathrow’s chief executive John Holland-Kaye told Reuters.

Britain, where the death toll from the coronavirus pandemic has nearly reached 130,000, reopened its borders to large parts of the world on Monday, scrapping quarantine for fully vaccinated arrivals from the European Union, excluding France, and the United States.

The move was welcomed by families divided by the pandemic and airlines strained by it.

“It is really awesome,” said 31-year-old medical writer Colleen Castro after collecting her luggage.

She and her husband had come to London to deliver some happy news to his parents.

“It’s been a really long time and, actually, I’m pregnant with my in-law’s first grandchild, so it’s really exciting to finally be able to be here and share that news with them.”

For travelers from Britain’s closest neighbor France, who must still quarantine on arrival in Britain due to London’s concerns over COVID-19, the opening up for other countries stung.

“It’s a bit scandalous for the French,” said Alain Jourdain, just before he boarded a Eurostar train from Paris to London, where he will need to spend 10 days in isolation in order to see his children. He last saw them in 2019.

“It’s very complicated, in particular all the paperwork to fill for the UK government.”

And it could get more complicated. The travel industry now faces a new headache with the government set to issue a COVID-19 warning against holidays to Spain, according to the Times newspaper.
