Twenty-four countries could be moved to a different part of the travel traffic light system at an update expected on Thursday spelling big changes for holidaying Brits.
While the final domestic coronavirus restrictions were lifted last month in the UK, people travelling into the country still have plenty of hoops to jump through.
When the government delivers its tri-weekly travel update, it will likely make a series of changes to countries in the traffic light system.
According to predictions by travel experts who have been crunching coronavirus case and vaccination numbers, 24 countries may be reclassified.
Restrictions may be lifted for some, such as Canada and India, while others may be downgraded due to a perceived increase in coronavirus risk.
As things stands, green list arrivals don't need to isolate, nor do ones from amber list countries who have had two coronavirus jabs.
People coming from red list nations need to fork out £1,500 to stay ten days in a quarantine hotel.
As much as speculation about the list can be helpful and informative, it should be noted that it's by no means an exact science.
The Joint Biosecurity Centre is responsible for deciding which country goes on which list.
It looks at a variety of factors including variants in the country, coronavirus case and vaccination rates, how good that country is at genomic sequencing and how good the overall data in the country is.
Red to amber
There are currently 60 countries on the UK's red travel list - the most restrictive category.
According to the PC Agency, four of the 60 red listed countries have rates that have fallen enough for a reclassification.
They are Bahrain, India, Kenya and Pakistan.
However, before you dust off your maps of the Middle East and Asia, it's worth remembering no country has yet been moved off the red list since it was introduced earlier this year.
The Joint Biosecurity Centre also appears to be particularly concerned about potentially harmful coronavirus variants, such as Delta which swept through India in the early summer.
Amber to red or amber plus
There are two countries currently on the amber list that have concerning coronavirus figures.
In recent weeks holiday hotspots Spain and Greece have seen things slide in the wrong direction.
Spain has a high infection rate of 356.4 per 100,000 people and has been reporting 22,000 cases a date - putting is just behind Russia and the UK on the worst hit list.
However, following a number of restrictions such as late night curfews and beach bans, the numbers have improved in the past few days and its beta variant count is dropping.
Greece also has a high rate of 182.17 per 100,000 and has similarly looked at restrictions freedoms in some holiday hotspots.
It had been tipped that both countries could be added to a new amber-watchlist, for nations at risk of being moved into the red group which requires hotel quarantine on return for 10 days at a cost of £1,750 for an adult.
But following a backlash by Tory MPs, ministerial concerns and complaints from the travel industry, Government sources confirmed there would be "no amber watchlist".
Now the Joint Biosecurity Centre has to decide whether to move them straight from amber to red, or add them to the extra special category that was created just for France.
Amber-plus to amber
Since last month our neighbours across the Channel have found themselves in a category of their own because of concerns about the Beta variant, which has proved more resistant to vaccines.
Transport Secretary Grant Shapps suggested things were going in the right direction for France .
Asked about the rate of Beta variant cases, he said: "It looks like it has been trending downwards... the Joint Biosecurity Centre will be looking at France and providing fresh advice on where that should sit in the system."
Amber to green
Analysis of vaccination and coronavirus rates by The PC Agency, a travel consultancy, has concluded that a dozen more countries are in contention to be turned green.
It is thought that Germany, Poland, Canada, Austria and Romania could be turned fully green at a government update in several days time.
PC Agency has also predicted that Bosnia, the Czech Republic, Hungary, Latvia, Lithuania, Slovakia and Slovenia will make the grade.
Experts say a further five areas currently on the amber list – Bhutan, French Polynesia, North Macedonia, Norway and Saudi Arabia – have low enough case rates to join the ‘green watch list’.
This alerts holidaymakers that certain destinations could be relegated to the amber list, where anyone not fully vaccinated has to self-isolate for 10 days on their return.
