Ministers are considering reimposing quarantine measures for those arriving in the UK from Portugal as coronavirus cases rise, sources have told the BBC.
The country has recorded more than 20 cases per 100,000 people in the past week.
Normally when a country surpasses that mark the UK government imposes 14 days of self-isolation on returning travellers.
Ministers are expected to reach a decision on the measures by Thursday.
Meanwhile, some travel industry leaders have suggested quarantine rules should apply to people returning from regions where case numbers are high – not whole countries.
It has been less than two weeks since Portugal came off the quarantine list and was put back on the UK’s safe travel list, following a sustained period of falling cases in the country that put it below the “20 per 100,000” mark that satisfied the UK.
But now holidaymakers are scrambling to return from the country amid fears the country is again about to be taken off the list, based on the latest data.
EasyJet has sold out all of its flights from Faro – which serves the Algarve – to airports in Britain for Wednesday, Thursday and Friday.
And British Airways is selling seats on a flight from Faro to Heathrow on Thursday for £554, while the same journey can be made seven days later for just £139.
Thousands of people have travelled from the UK to Portugal since the country was added to the UK’s quarantine exemption list on 22 August.
Portugal has recorded 21.1 virus cases per 100,000 people in the past week.
The UK considers imposing quarantine on travellers when a country’s infection rate exceeds 20 cases per 100,000, over seven days.
Over the past month, so-called travel corridors – which allow people to travel without having to self-isolate on their return – have been scrapped between England and at least 18 countries and territories.
Ministers have said this cautious approach prevents coronavirus cases being imported.
Algarve tourists
Andrew Flintham, head of Tui UK, has said the government should consider “regional travel corridors” – meaning quarantine measures would apply to people returning from regions over whole countries.
He said there were fewer cases in the popular Algarve, where most tourists are, than elsewhere in Portugal.
His comments came as the boss of British Airways’ parent firm, Willie Walsh, accused the government of using “arbitrary statistics to effectively ban 160 countries and in the process destroying the economy”.
The “ever-changing” quarantine requirements meant “the UK has officially hung up the ‘closed’ sign”, he said, writing in the Times.
Using the example of Leicester, the first area in the UK to be placed under local lockdown, Andrew Flintham told the BBC: “In the UK we have a slightly different policy in the fact that we don’t lock down the whole UK when the Leicester rate goes up.
“Can we apply the same kind of principle to almost allow us to operate to those places where the rates are low or are within those thresholds?
“We don’t want to put anybody in danger but clearly it is not the same everywhere in a country,” he added.
Last week, Switzerland, Jamaica and the Czech Republic joined France, Spain and a number of others on the UK’s quarantine list.
UK tourists have spent thousands of pounds on new flights and ferries, and endured long drives in a race to get home before quarantine measures kick in.
The government has not commented on whether requirements for arrivals from Portugal will change again.
Tourists’ tale: ‘A mad stampede’
Neil Millington, who is on holiday in Madeira with his girlfriend Vitalija Mockeviciute, believes it would be ridiculous to put the Portuguese island on the quarantine list.
“There are an awful lot of English people here,” said the 51-year-old, who works in the hotel industry.
“There will be a mad stampede to get a flight back.”
They are due back from Madeira on Monday so it is likely they will have to quarantine if they stay until then. Currently they are weighing up the option of coming back early.
Every visitor to the island is tested for the virus before or on arrival, and must isolate until the results come back. Neil and Vitalija got theirs back within 12 hours.
“It is a fantastic system they have here for Covid testing,” he said, pointing to the island case numbers of 157 in total.
Every year, more than two million Britons visit Portugal, making up the largest number of overseas tourists to the country.
Most head to the Algarve in the south, drawn by sunny Atlantic beaches, picturesque fishing villages and golf courses.
Over May and June, the Portuguese government reopened its restaurants, coffee shops, museums and beaches. Hotels have mainly reopened, but nightclubs remain closed.
The government has warned that stricter measures will be put in place in mid-September as pupils return to school and some workers return to offices.
As of 31 August, the UK recorded 24 coronavirus cases per 100,000 people over the past fortnight while Portugal recorded 35.7, according to the European Centre for Disease Prevention and Control.
