SCOTS holidaymakers could be able to fly to some destinations on the continent and avoid any coronavirus checks and quarantine, so long as they do not leave from Glasgow, it has emerged.

The development came as the prospect of “travel corridors” with certain countries appeared to be growing with Turkey suggesting it had already agreed a provisional date in July to establish one with the UK.

The European Aviation Safety Agency[EASA] has drawn up a list of 13 high-risk UK airports to highlight those parts of the country with the highest levels of Covid-19.

While airports such as Glasgow, Heathrow, Gatwick and Manchester are on the list, others, including Edinburgh, Inverness or Aberdeen, are not.

Increasingly, EU countries, many of which rely heavily on the tourist trade to bolster their economies, are eager to relax restrictions as their coronavirus infection rates diminish.

On June 15, Greece will open its border to tourists for the first time since it began its lockdown in March. It says that it will use the EASA system to help it judge which travellers from which airports will face the strictest tests with some travelling from low-risk ones not expected to face any.

Harry Theoharis, Greece’s tourism minister, said: “For the rest of the airports, testing is mandatory and for a certain amount of days you wait for the test results.

“If it is a negative result, then it is effectively a self-imposed quarantine of seven days but you can go ahead to your destination. If, however, it is a positive result, then it is a supervised quarantine for longer than seven days.”

However, a spokesman for the EASA said there was a deal of confusion about its listing system and that it was not meant to suggest travel restrictions or public health measures like quarantine but rather “simply to indicate routes on which extra disinfecting of aircraft should take place to avoid the spread of Covid-19”.

From Monday, the UK Government will introduce a 14-day quarantine for anyone travelling to Britain, barring a few exemptions, in order to stop any infection being imported into the country as it attempts to reduce the spread of Covid-19 at home. The policy will be subject to a three-week rolling review.

However, Boris Johnson has made clear he is “actively considering” the idea of “travel corridors”.

On Tuesday at the daily Downing St briefing, the Prime Minister said: “Of course, we will explore the possibility of international travel corridors with countries with low rates of infection but only when the evidence shows it is safe to do so.”

But already there are suggestions that a provisional July 15 date for a resumption of travel between the UK and Turkey has been set.

Other destinations such as France, Spain, Portugal as well as Greece are also thought to be possibilities for similar arrangements.

Given the UK has one of the highest infections across Europe – earlier this week the daily number of deaths was more than the combined EU total – it might have been expected that countries in the Med and beyond might be wary of opening any travel corridor with Britain during the pandemic.

However, one Turkish Government official claimed an agreement with the UK was close, even suggesting a provisional date for the resumption of travel between the two countries had been set for July 15.

“The two sides are in close contact. The UK is a very important country for us,” he told the FT, stressing any final decision would depend on the level of British infections. Last year, 2.6m UK holidaymakers travelled to Turkey.

Spain, which is set to ease its 14-day quarantine from July 1, is in discussions with the German Government about a travel corridor.

But Reyes Maroto, the Spanish tourism minister, said: “We trust it will be very soon that we can receive British tourists.” The UK is Spain’s largest tourism market with last year more than 18 million Britons holidaying there.

Mr Johnson’s spokesman, when asked about the suggestion of a provisional holiday resumption deal with Turkey, stressed that he did “not have any details of any specific discussions,” but pointed to the PM’s desire to “work with our European partners” on the issue of travel corridors.

Meanwhile, the European Commission, noting how the coronavirus situation was “fast improving,” has called on all EU member countries to have lifted their border restrictions by the end of the month and allow passport-free travel across the bloc.

Ylva Johansson, the Home Affairs Commissioner, said: “We are coming very close to a situation where we should lift all the internal border restrictions and border checks,” noting: “A good date should be the end of June.”

Elsewhere, British Airways’ parent company said it was considering taking legal action against the Government’s decision to impose a 14-day quarantine on international arrivals.

A disgruntled Willie Walsh, IAG’s Chief Executive, described the policy as “terrible” and warned that it had “torpedoed our opportunity to get flying in July”.
